The Fast-Moving Crab Both Is You And Destroys You – The Always Dreaded Diagnosis Of A Malignant Cancer Destroys All Your Dreams And Plans, And Changes Your Life Forever

A lot of folk wonder if social media and its rapid growth and development to become in contemporary times almost part and parcel of our daily life is a good or a bad thing. While this argument will doubtless continue for many years further, one positive chance associated with social media such as Twitter, is to allow the previously ‘unseen masses’ of society, whatever their age, background, intellect, or social standing, to have their say about anything they feel, or write a narrative tweet or series of tweets about their own life, and even if they only have ten followers, they all have an audience. One thing I have noticed more often recently is folks describing in detail on Twitter when they are not well, and what the cause of their illness is, from testing positive for Covid to coming ‘clean’ after an alcohol addiction. Its also noticeable that these health-related posts get a lot of likes and encouraging tweets when they are posted. Particularly poignant are the announcements on Twitter of folks who have had a cancer diagnosis and who announce this publicly to their followers, and then continue to tweet further over the next few months or years chronicling their small triumphs and tragedies, or describing how they are ‘fighting’ their ‘body invader’ and will not be ‘defeated by it’. Sadly, a lot of these Twitter ‘life stories’ end up with a note posted to their Twitter account from a partner or family member, saying that the person who usually wrote the tweets had died, as the final post of these tragic tales. Cancer has always been a subject of interest and concern to me, both as a person from a family with a history of cancer who has young children and a desire for more life to be lived, and as a medically trained doctor and scientist. As a teenage boy, one of my most vivid memories was of my father telling me the story of how his own father had died. He described how my grandfather had been driving into town – Durban in South Africa – with my father, who was in his early twenties, when he suddenly started vomiting up blood in the car. As my father told it, they only had handkerchiefs to clear up the vomited blood, and after doing so as best possible, he swopped positions with his father in the car and drove him to the nearest hospital. Sadly, medical tests showed my grandfather had terminal stomach cancer, and he died not long after this vomiting event in the car. What I remembered was the emotion and feeling my father had when telling the story, and it was obviously clear that both the shock of the experience of having the driver of a car he was in suddenly vomiting blood, and the knowledge that this person was his father who was seriously sick, had affected him for many years afterwards. Around twelve years ago my father, who lived six months of the year in the UK and six months in South Africa, boarded a plane to start a routine block of time living in South Africa. He had been feeling unwell for a few weeks before leaving, complaining of a nagging chest cold and a feeling of being exhausted all day, and a visit to his local doctor had resulted in a diagnosis of a chest infection for which he was sent home with antibiotics. On the plane he started coughing up bloody sputum, and this frightening development continued for the rest of the flight and after he had landed in Durban. He was immediately taken by my mother and siblings to hospital, and his chest scans showed the dreaded signs of late-stage metastatic cancer – big ‘cannonball’ lesions in both his lungs, and I think in his liver too – of a tumour that was finally diagnosed as being a melanoma (skin cancer), of which the primary site was never found. He went on a course of chemotherapy and what was then a new form of cancer treatment called immunotherapy, and these treatments made him feel frightful – nauseous, night sweats, itchy skin and other terrible side effects – but the treatments had no discernible effect on his cancer trajectory, and he died a few months later after a terrible time leading up to his death. I therefore clearly have cancer ‘in the family’, and there is a high chance I will one day get a similar dreaded cancer diagnosis that will cause me to ‘shuffle off this mortal coil’ in a painful and terrible way, unless a heart attack gets me first. In this article therefore we will examine cancer as an entity, and whether it can ever be ‘defeated’, and how it affects those that it does like a crab ‘locking its claws into the tissue of its victim’ with a deadly and ever tightening grip.

In the actions of the physical components of the body, which are necessary for maintaining life processes and functions, there are two things that are miraculous to me. The first is that from a genetic code perspective, one’s body grows by multiplying cells controlled by a genetic ‘map’, which over the years of childhood and adolescence increase in number and type until eventually a fully functional adult human is created, with a body that is astonishingly complex and with many different organs and tissues, and at an even deeper level millions of cells operate synchronously both spatially and temporally in order to maintain physiological function and keep us ‘alive and ticking’ in a manner which occurs in a similar way in all of us humans. The second miraculous event is that the genetic code and cellular structures know when to stop growing, and cells know when to stop dividing, when the genetic ‘map’ is complete in the physical realm and no further growth is needed. This is controlled by a still-not-well-known complex system of negative feedback mechanisms, either from suppressor genes which ‘switch off’ gene function, or by protein structures made by the genes themselves which similarly ‘switch off’ genes or reduce the expression of genes (i.e., stop it producing more proteins) when activated as part of an ‘epigenetic’ feedback loop (basically, non-genetic structures acting on genes to attenuate the production of further non-genetic structures by the genes). When a gene gets damaged, there are also protein structures – telomerases – which either ‘fix’ the damaged gene, or cause ‘senescence’ – cellular death of the structure made by the faulty gene. All these control mechanisms keep us well and in a steady ‘homeostatic’ state of optimal existence, which enables us to live our lives both healthy and cancer-free.

Unfortunately, when a cancer ‘begins’, something in one of these ‘suppressive’ mechanisms goes wrong, and the gene that is ‘reactivated’ by the lack of suppressive activity starts creating protein material at increasing speed, and eventually a visible growth of particular tissue activated by the faulty gene become evident, and causes pressure effects on surrounding tissues which often results in the first symptoms one ‘feels’ as a result of a cancerous growth, or by a still not well-known process, starts damaging and destroying cells around it by releasing enzymes or other activating mechanisms that cause cellular damage around and in the tumour tissue (a growing tumour that is well circumscribed is usually ‘benign’ and can only kill one by pressure effects, while if a tumour starts scavenging and damaging surrounding tissue it is generally called ‘malignant’, and is clearly a worse situation and worse diagnosis to have. Cancers are defined by the type of tissues which are multiplying abnormally – for example when epithelial cells (those cells that line the organs of the body) it is called a carcinoma, when lymph gland cells it is called a lymphoma, and when bone or surrounding bone connective tissues cells, it is called an osteosarcoma. If it is found in a specific organ, that organs name is added to the name – for example a lung carcinoma is a cancer of the epithelial cells of the lung, and a hepatocarcinoma is a cancer of the epithelial cells of the liver. For reasons that are still obscure to us, different cancers develop at different rates and kill folk more quickly or more slowly – for example pancreatic and liver cancer are particularly speedy and kill quickly, whereas prostate cancer takes years, even decades to develop. and several folks with prostate cancer live to an age where other age-related illnesses kill them. Similarly, some cancers respond better to treatment than others – for example a testicular cancer has a relatively high success rate from treatment, whereas lung cancer and melanomas once they have metastasized seem to have very low response rates to treatment. Having said that, it appears also dependent on the individual tumour themselves, with some folk lasting several weeks, while others last several months or years, with the same diagnosis and cancer type and stage.

The first million-dollar question associated with cancer (the second being how to treat it) is what causes the gene to mutate or the suppressor functions to ‘go wrong’ and begin the terrible process of abnormal cell division, malignant growth into surrounding tissue and eventually the death of both the surrounding organs and the human being eventually themselves. Many different causes have been suggested. Radiation of cells has been suggested to be a major factor in causality, given the number of folks who developed cancer after the atom bomb explosions in Japan during World War 2, or folks at Chernobyl and Fukushima and other places which have had nuclear disasters and subsequent radiation-induced damage to folks living in surrounding areas. Toxic agents like tobacco and smoke inhalation are also thought to be carcinogens (cancer causing substances or agents). Asbestos in building structures has been linked to cancer, as has exposure to Teflon coated products. Infective agents have also been linked to cancer, with several oncoviruses (viruses causing cancer) including human papilloma virus (predominantly cervical cancer), Epstein-Barr virus, Hepatitis B or C, and many others are linked to cancer development, as have infection with parasites such as schistosomiasis – which is more commonly associated with bilharzia – suggested to cause carcinoma of the bladder. Many types of food have been thought to be linked to cancer – for example eating betel nuts being linked to mouth carcinoma – and examples of whole population studies of countries whose people ingest country-specific diets such as the Japanese who have a high salt and high fish and rice diet show them to have a higher incidence of stomach cancer, while folks in the USA, who have more red-meat in their diet, have more bowel cancer than the Japanese, though in contemporary times, as Japan changes to a more Western diet, these differences are becoming less. Interestingly, folks who immigrate to a new country tend to pick up the same levels of cancer types prevalent in their new country rather than in their old country within a generation of living there. I have to say I am a great believer in Occam’s rule in science, which suggests that the simplest answer to any question is usually the best, and when there are so many suggested causes of cancer initiation, I do believe this means we have no real idea of exactly what triggers cancer development definitively (at best these data show that many factors could be involved), and research done by future generations will give us better answers then we have now, and perhaps also provide us more peace of mind by reducing things we currently worry about as being potentially causative of cancer such as those described above.

Whatever its cause, the most important beneficial outcome of a cancer diagnosis is identifying the tumour as early as possible. A major problem though for early identification is that most symptoms of cancer are generic (could be caused by several different illnesses and pathologies), and by the time one has specific symptoms, the cancer has become late stage and thus more difficult to treat successfully. Paradoxically also, because most folk are so scared of having a cancer diagnosis, they put off getting a check up on worrying symptoms or signs, and go for a medical check-up when it is too late, or when a major medical emergency results from the primary tumour or from one of its metastatic sites, such as a seizure from a brain tumour, or like my father, coughing up blood on an aeroplane. The early signs are often nebulous – again, in my father a cough that wouldn’t go away, in bowel cancer weight loss and bowel habit changes which are ignored as being caused by old age or stress, or in prostate cancer signs of changes in urinary habits, again, that are often put into the ‘I’m getting old’ category of causality and ignored until too late. Often cancers are picked up at routine checks or when one needs a medical certificate of wellness for travelling or moving to another country, or other such unexpected occasions. In young folk and children, it is even harder to diagnose early, as they have so many aches and pains which are generally regarded as ‘growing pains’, and children are often sick from respiratory and gastro-intestinal infections, which also confuse diagnosis. When a diagnosis of cancer is suspected, a medical practitioner will look just not at the local symptoms, but will do whole body scans or a wide variety of blood tests, to see whether it has spread around the body, and the cancer is ‘staged’, with stage one being very localized and more easy to treat, and stage four being very advanced and spread to several body areas, and obviously stage four has a far worse prognosis for successful treatment than stage one – but again, as so few folk go to the doctor with mild symptoms, it is sadly often the case that cancer is picked up ‘too late’ / at a stage three of four level. We will discuss cancer treatment and its problems shortly, but sadly, while there has been some improvement in cancer survival rates over the last fifty years, most of this improvement has been due to earlier diagnosis and more energetic screening programs, rather than due to successes of the treatments currently available themselves.

The mainstay of treatment of nearly all tumours (except of course blood-related tumours) is surgery. Particularly if one has a stage one tumour which is well circumscribed and where there is no evidence of tumour metastasis, one has a good chance of surgical removal of the entire tumour occurring (usually incorporating some healthy tissue around the tumour as a precaution), resulting in a successful ‘cure’, at least in the short term. Sadly though, cancer is the Latin word for ‘crab’, and cancer is named such because like a crab it is not often round and well circumscribed but rather has ‘claws’ of malignant tissue reaching up unseen to the naked eye into surrounding tissue, or spreading to lymph nodes, or to areas further away, and surgery may miss some of the cancer, with the predicable disaster of the tumour growing back at some time point after the initial operation. Cancers also for some reason still not identified cause growth and enlargement of blood vessels into their centre (and have increased level of glucose metabolism which occurs via unusual metabolic breakdown pathways – known as the Warburg effect), which again makes them look like a ‘crab’, and sadly, increases the risk of the cancer cells breaking through into the blood stream and moving off into other areas of the body as metastatic ‘islands’ of tumours, which can grow big themselves in the secondary tissues or organs they lodge in (the second main way metastasis happens is via the lymph nodes). I will never forget when I was a final year medical student at the University of Cape Town, watching a breast tumour removal at Groote Schuur hospital performed by one of the world’s leading breast cancer surgeons, Professor David Dent, from a patient from a rural area of South Africa who had ignored a breast lump, and when David operated to remove it, the cancer was the size of a cricket ball, if not larger. What struck me most though, and which has been the source of several nightmares I have had, was that there were huge blood vessels coming out of the cancer centre (or going in), and David had to spend more hour’s resecting (cutting and tying off these vessels so they did not keep bleeding) these vessels than he did removing the tumour. Even as one of the best surgeons in the world, he could remove the tumour perhaps better than most other surgeons could, but even he could not save the patient, as sadly she also had metastatic lesions all over her body emanating from the breast cancer, and was sent home for palliative rather than curative care a few weeks later.

The other main types of treatment are radiotherapy and chemotherapy, and in more recent times, immunotherapy (stimulating the patient’s own immune system to ‘fight’ the cancer) has become used as a treatment source in some tumours. But, sadly radiotherapy and chemotherapy, which focus on using either radiation to ‘burn out’ the tumour, or which kills the tumour with drugs made up of different drugs which are toxic to the cancer tissue, have the problem of being somewhat ‘blunt’ treatment regimens, and often damage normal tissue, and have many negative side effects themselves, as described above in the first paragraph regarding my father’s cancer treatment and death. They do seem to work better in some cancers compared to others, but as described above, it is not clear how much their use has improved cancer treatment success, beyond that generated by early diagnosis via improved screening methods. I have to be honest and say at this point in time, when I am well, hale and hearty, and having learnt a lot about these treatments, if I had a late stage cancer diagnosis, I am not sure I would sign up to have either radiotherapy and chemotherapy like my father did, due to their major side-effects and because they may give one at best a few months more time alive by reducing the size of the tumour, but those few months extra will be lived with all those negative side effects associated with their use. But, if one of my children or my wife had a cancer diagnosis, and a good doctor I trusted said that chemotherapy or radiotherapy would help them / give them a chance, I probably would not be so bold (or foolish) and would allow the doctors to give these treatments a try, even if the data on their success rates (or rather lack of success rates) is to me appalling. I am sure most folk don’t share my negative perception of chemotherapy and radiotherapy, and one must remember that folk like the world champion cyclist Lance Armstrong was diagnosed with a stage four cancer with metastases in his brain, liver and other organs, and survived after being treated with a combination of surgery, chemotherapy and radiotherapy, and more than fifteen years later after initial diagnosis is still cancer free – though of course he had testicular cancer, which as I have said above, seems to ‘respond’ better to the available treatment regimens than other types.

One of the saddest issues related to folks who develop cancer is that they are often ‘preyed upon’ by ‘quacks’ selling strange supposed ‘cures’ for their cancer and given that they have such a strong desire to live, they often accept these offers of assistance, and pay large sums of money for treatments with no benefit whatsoever, and even use these in place of more conventional radiotherapy or chemotherapy and even occasionally surgical management. A case in point was the actor Steve McQueen, who was diagnosed with a lung mesothelioma with secondary tumour spread to his abdomen and other parts of his body, and who refused conventional treatment and was treated by a ‘quack’ using bizarre interventions like coffee enemas, frequent shampooing of his body, injection of the ‘live’ cells of sheep and cows into his body, and other bizarre treatments, for which he paid thousands of dollars each month. The ‘quack’ boasted he would be cured shortly, but of course these ‘treatments’ had no effect whatsoever on the cancer, and McQueen’s primary and secondary tumours grew rapidly and he died not long after receiving these treatments. There are also a number of ‘quacks’ littered across social media who suggest that they have come up with either a diet, or way of life, or some strange therapy, that if used by healthy folk on a continuous basis, will prevent the subscriber who uses their products from developing cancer. There is sadly no real evidence for any diet or way of life being more protective than others (apart from stopping smoking), and just about every food type has at one time been linked to cancer, or paradoxically, has been punted as being curative of it. Fear of death and paranoia regarding the potential causative effects of daily life on cancer genesis probably drive folks to take up these advertised ‘anti-cancer’ lifestyle choices, which are costly and generally demand a high level of asceticism, but sadly with no real proven benefits in nearly all cases. Sadly, it is very difficult to stop these charlatans and quacks from ‘plying their trade’ on a group of folk who are prone to believe them due to the challenging and terrifying situation they find themselves in when receiving a cancer diagnosis, and one can only be hopeful that in the future, legislation can be passed to prevent the activities of these pathological purveyors of nonsense, but given as described above, the traditional methods of attempting to cure cancer are so tenuous and statistics of cure so bad, that there will always be believers in their nonsense in cancer sufferers who are looking for anything that will give them hope.

Another unfortunate way folks with cancer are ‘preyed upon’, very sadly, is by some cancer specialists, who inflate the price of drugs needed to ‘treat’ cancer, and then encourage folk even if they have cancers with little reactivity to any treatment, such as melanomas and pancreatic cancers to use these inflated cost drugs, knowing that the folks with cancer will do anything, and pay anything, to be given a chance to live longer or ‘beat’ the cancer and re-attain their healthy state. Again, very sadly, parents with children diagnosed with cancer are another group who are ‘easy prey’ for avaricious cancer specialists who offer a cocktail of drugs and therapies at inflated prices. There is nothing much that can be done to attenuate what is for me terrible practice from medical practitioners involved as while it is surely immoral, it is not illegal, other than to be sure to ask the treating physician if the treatment they suggest is the lowest price treatment, or whether another drug of similar efficacy but less cost is available, even though one may worry that one is asking for inferior treatment. With all the above examples, it is obvious that there are challenges facing folks recently diagnosed with cancer beyond just managing the cancer diagnosis itself, such as being sure one accepts help from folks one can be sure have one’s best interests at heart and avoiding the charlatans and sociopaths who cross your path and try and make a profit out of your misery and need to feel hope.

Whatever the cause, or type, or stage, of cancer, being diagnosed with it is one of the most challenging things a person can have to deal with in their life. Even waiting for test results to come back for cancer scans can cause dramatic psychological upset, fear and anxiety, and a diagnosis of cancer for most folk is truly a life changing event, with everything one planned for in the future being ‘thrown out the window’, and suddenly one has to deal with one’s own mortality as a real rather than ‘hypothetical but unimaginable’ future event. There are very high rates of depression and increased incidence of suicide in those diagnosed with cancer. Folk can go through the Kubler Ross stages after being given a cancer diagnosis – denial, anger, bargaining, depression, acceptance – but the progression between these is not always linear, and for most folk life is from a mood perspective, a very much fluctuating ‘event’ post-diagnosis, given that there are periods of hope, periods of great illness when having chemotherapy and radiotherapy, and periods of despair when told treatments are not working as they should, and even when someone is one of the fortunate folk who get told they are ‘all clear’ of the cancer, sadly it returns in so many folk that one cannot feel ever that one is completely ‘cured’, and folk in remission always know that it could return, and have high levels of anxiety for every symptom they feel or sign they see in their body which may indicate their cancer is returning. An interesting psychological occurrence is that most folk tend to externalize the cancer as something that has ‘attacked them from outside’ and that it is not of their body, perhaps because it is difficult to ‘declare war’ on one’s own body when it has let one down so badly as it has when cancer develops from and in one’s own organs. Sadly, most folk, whether a few months later like my father, or several years later for folk with prostate cancer, will be told by their doctor that nothing more can be done to treat their cancer, and that their care going forward will be palliative – relieving pain and complications of the cancer, rather than trying to cure the cancer itself – and that such folks need to prepare themselves for their imminent death as best they can. As it goes, with good palliative care, the end stage and dying process can become relatively positive, given one can give morphine / painkillers as needed, and ensure the last days of the cancer stricken person to be as easy as possible as they say goodbye to their close ones and to their own life itself, though of course, even if folk die bravely and pain-free, nobody wants to die, and it is a shattering process both for the person dying, and perhaps even more so for those who love them and have to watch them die.

Due to a family feud, I did not see my mother for seven years, until two weeks before she too died of cancer in her mid-seventies. I flew across from New Zealand, where I was working then, to Durban, to say my goodbyes to her, and had a final cup of tea with her, and we cried together and I said my goodbye to her and left, never to see her again. She was so thin and delicate, with a belly swollen tight with fluid due to secondaries in her liver and abdomen, and each word she spoke was difficult for her to get out – the cancer destroyed her physically and she was a shell of a human being when she died. I remember also the last time I saw my father twelve years ago – he gave us a huge wave and his customary ‘yay for the good guys’ shout as we drove away from his house in Durban, trying to stay positive even though he was gaunt, pale and sweating from the treatment cycle which he was currently on. I remember being called when he died and thinking both how sad it was, yet relieved that he was peaceful again, after the terrible last few months when he was ‘fighting’ the cancer that killed him. Given my family history, I am sure I too have this terrible diagnosis and end of life ‘program’ ahead of me (though of course while no way of dying is pleasant, to me there are far ‘worse’ ways to die than by cancer, for example Locked-In syndrome, where one’s whole body is paralysed yet one’s mind is fully cognitive to the end, is to me the absolutely ‘worst’ way to die). When I was young, this knowledge used to make me wake up at night sweating with fear, but paradoxically the older I get I seem to have come more to terms with it, and await my outcome and final death diagnosis, whatever and whenever it will be, with a greater degree of stoicism. However, having said this, even with my experience of being a clinician and researcher myself, I still occasionally don’t go to the local GP for a check-up even if I have symptoms that bother me, so at a deeper level I am surely still scared of a cancer diagnosis, even though perhaps not as much as when younger. As described above, even though medically trained, I must be honest and say I would like to think I would refuse chemotherapy and radiotherapy if diagnosed at a late cancer stage and use the last bit of time to enjoy life as much as possible with my family and friends, until the final day of my life arrives and I take the journey into eternal darkness, but let’s see what happens and what decisions I make when a bad cancer prognosis becomes my own fate. As a medical student we had a lecture on cancer given by an old German doctor, who said that if you have a patient with stage four terminal cancer, why stab them with needles each day to check on the status of their blood parameters, and by doing so trying to causing them a lot of pain, only to potentially save them for at best an extra month or two – rather send them home to plant the next crop of corn, and get things ready for life’s next cycle (meaning get one’s affairs in order for one’s children and their future) and I have never forgotten this, and hope when my time comes I will do such. For many of us the crab is floating in the shallow waters just beyond where our toes are dipped in the water, and if or when it bites, it is surely the start of a turbulent journey across the bay to the land on the other side…

Anorexia Nervosa And The Eating Disorders – A Tragedy of Faulty Mirrors, Control Or the Lack of It, And A Walk Back To The Abyss

I was in a gym last week and noticed an emaciated women running on a treadmill, who was so thin that individual muscles and bones were visible in her exposed flesh around her gym clothes. I wondered if, wearing my clinical hat, I should speak with the gym staff about her, given it was clear she either had a chronic disease that caused profound secondary weight loss, or she had an eating disorder, most likely anorexia nervosa. I have noted with concern when watching cycling races how thin elite professional cyclists are during long stage races, and was interested when reading the autobiography of one of the world’s best cyclists that they believed that both themselves and several of their cycling colleagues would probably satisfy the criteria for a full-blown eating disorder diagnosis, and that they had battled with food ingestion both during their career, and even after they had stopped being competitive. As a teenager I was sent to boarding school, and didn’t settle well into the strong routine and rules based environment that boarding schools require in order to function, and I stopped eating as a ‘silent protest’ to get attention to my dislike for my environment. I eventually cut my weight to almost zero body fat, and folk wondered if I had a bone fide eating disorder, though fortunately when my parents accepted that I could not continue at the boarding school in my state of refusing to eat and resultant massive weight loss, they took me out and put me into a day school, and almost immediately I started eating again, my weight normalized, and the problem was pretty much resolved for me. Seeing the lady on the treadmill, reading the book on the eating travails of the elite cyclist, and reflecting on my own weight reduction story of my youth, got me thinking about anorexia nervosa, what causes it, and why some folk both start to refuse to eat food, and continue to do so, even if it causes them to literally starve themselves to death in an environment of plenty, and with so many of their loved ones around them willing them to eat normally, put on weight, and live a ‘normal’ life as they apparently used to do.

The symptoms and signs of anorexia nervosa were first described in medical texts as early as in the 1600’s, and was termed anorexia nervosa in the late 1800’s. The term is Greek in origin, with ‘an’ describing negation and ‘orexis’ describing appetite – so literally a psychological negation of appetite. Its classical symptom is obviously food restriction resulting in rapid weight loss, and it can be accompanied by compulsive behavior such as excessive exercise (in order to use up calories and thereby lose weight), a paradoxical preoccupation with food, recipes, or cooking food for others which is not consumed by themselves, food rituals such as cutting food into small pieces and not eating it, refusing to eat around others or hiding and discarding food, and purging themselves with laxatives, diet pills, or self-induced vomiting in order to attenuate the effect of eating any food whatsoever, no matter how small the portion (to note these purging actions also occur in its ‘cousin’ disorder, bulimia nervosa, but there is usually not the marked food restriction in bulimia nervosa, and weight loss may not be evident in folk suffering from bulimia nervosa). There are a number of other signs which are diagnostic of anorexia nervosa, including low body mass index for one’s height or weight, amenorrhea in females, the development of lanugo (fine, soft hair growing over the face and body), intolerance to cold, halitosis (bad breath), orthostatic hypotension (low blood pressure when lying down), chronic fatigue, and changes in heart rate (either slowing down or speeding up). But, most of these may be related to the chronic and extreme weight loss, rather than to anorexia nervosa per se. Clinicians have to be very cautious before diagnosing anorexia nervosa to be sure to exclude a wide variety of clinical disorders that can lead to profound weight loss, including cancer, type 1 diabetes, thyroid hormone disorders, and a host of other clinical conditions. Anorexia nervosa is thought to occur in approximately 1-4 percent of females, and 0.5 percent of males, and often begins during the teenage or young adulthood years.

There is much debate still about what causes anorexia nervosa. There has been an increased incidence of the diagnosis of anorexia nervosa in the last 50 or so years, and this increase has been correlated with increase in social pressures, particularly on females, but more recently on males too, for the ‘ultimate body’, with most cultures increasingly favouring a slender shape and the ‘size zero’ model, where clothes and fashion are displayed on waif-like models. This is theorized to put pressure on most folk to be thinner than what is possible for the vast majority of people. But, correlation is not causation, and the counter-argument to this social theory would be that 96% of women and 99.5% of men see similar fashion images and models and do not develop anorexia nervosa. There is a strong familial link to it, with twins and first degree relatives of someone diagnosed with anorexia nervosa having a significantly higher chance of developing the disorder. It has also been suggested that the prevalence of anorexia nervosa is higher in athletes doing sports that require weight control, such as gymnasts, runners and cyclists, and in those folk whose careers similarly require weight regulation, such as ballet dancers and jockeys. It has also been suggested that folk with gastrointestinal disorders such as inflammatory bowel disorder and coeliac disease may have a higher prevalence of anorexia nervosa, due to the increased requirement to be ‘aware’ of what food types are ingested if suffering from other of these challenging gastro-intestinal disorders, and indeed eating any food whatsoever may initiate their symptoms. There has been an increase in interest in ‘extreme’ diets such as the keto, carnivore, and vegan diets, amongst others, and it has been suggested that engaging with such diets may precipitate the development of anorexia nervosa, or indeed be a ‘mask’ for those with eating disorders to ‘hide’ behind as a label that would allow them to explain their weight loss and extreme thinness in a way that was more socially acceptable than telling those around them that they have anorexia nervosa, or allows folk suffering from the disorder to feel part of a group of similar food conscious folk.

Anorexia nervosa would be easy to diagnose, treat and manage if the disorder was as simple as that described in the paragraphs above. But, a major confounding issue is that a high percentage of folk who suffer from it deny having anything wrong with themselves, deny having an eating disorder, and some resist being treated to the point of requiring to be restrained and force-fed to keep them alive. It sounds terrible that folk have to be force fed against their wishes (and some doctors have an ethical problem doing so), but unfortunately anorexia nervosa has the highest mortality rate of any psychiatric or psychological disorder, around 10-12 times that of the general population, with the risk of committing suicide being 50 times higher. Anorexia nervosa sufferers literally starve themselves to death, or commit suicide while doing so, and there is a high recidivism rate, with only half of the folk who have it ‘recovering’ (if they ever do), with the rest relapsing or becoming chronic and a permanent ‘way of life’ until death intervenes. So something is clearly desperately ‘wrong’ in these folk, who either know about it and acknowledge it, know about it and don’t acknowledge it, or not know that they have the disorder and perceive themselves to be well – clearly the latter group being the most challenging to treat, though all three groups require major psychological assistance and intervention. Anorexia nervosa is classified under Feeding and Eating Disorders in the ‘bible’ / official manual of Psychological disorders (known as the Diagnostic and Statistical Manual of Mental Disorders – DSM5), but there is a high prevalence of other associated psychological disorders, including obsessive-compulsive disorder and obsessive compulsive personality disorder, anxiety disorder, and depression. An array of other psychological disorders have also been linked to anorexia nervosa, including borderline personality disorder, attention deficit hyperactivity disorder, autism spectrum disorders, and body dysmorphic disorders, and while some of these linked disorders require further research to understand their prevalence and linkage to anorexia disorder, it is thought that having these comorbidities worsens the prognosis for folk suffering with florid anorexia nervosa.

With all these challenging psychopathology and comorbidity factors, three key issues appear to be fundamental to anorexia nervosa. The first is precipitatory factors, the second loss of interoceptive (body state) awareness, and the third perception of loss of control in folk with the disorder. It is thought that a stressful incident in one’s past life, or a change in circumstances for an individual already predisposed to develop the disorder, or by being in a sport which requires weight regulation, can precipitate the development of anorexia nervosa in a susceptible individual. Sadly, a number of folk who develop anorexia nervosa have a history of childhood trauma, including abuse, parental divorce, or a conflict-filled environment, and a study published last year found there was a twenty five percent incidence of sexual abuse during childhood reported as occurring before the onset of anorexia nervosa. Equally, a change of environment that is challenging, such as moving geographically, or going to boarding school, or the death of a parent or sibling or loved one, or being teased about one’s body shape in childhood or adolescence, may also be precipitatory factors. While difficult to prove direct linkage as a response to these psychologically ‘shattering’ events, what appears to happen as a result of these traumatic challenges is that a process of ‘disembodiment’ occurs (also described as ‘interoceptive loss’) where one’s body image is altered, or one does no longer ‘recognize’ one’s current body image, perhaps as a way of ‘denying’ the trauma that was done to it as would have occurred as a result of being sexually abused for instance. It has also been suggested that folk with anorexia nervosa undergoes a ‘loss of emotional self’, where one no longer recognizes ones emotions and feelings, in a similar way, and for similar reasons described above, as why one no longer recognizes one’s physical body. Lonnie Athens, one of my most admired Psychology researchers, has suggested that one cannot have too weak a sense of self, as one would not be able to have a stable sense of self-identity if so. However, he suggested that with a profound change, such as being the victim of a violent episode, divorce, loss of a job, or some other profound experience, for which the individual has no prior frames of reference or experience of, and which their current self-identity system (whatever this is) cannot provide interpretation of or makes sense of, resulting in changes to the sense of self similar to that found in folk with anorexia nervosa. In his model, the factors which set the sense of self in the brain become confused in a crisis for which there are no previous precedents to benchmark the current experience against. Because of this, the sense of self become fragmented, and replaced by a different sense of self, if the individual is able to make sense of what happened to them and ‘move on’ from what happened, but if not, remains permanently fragmented, and folk develop into a permanent state of sense of self ‘flux’, in which the individual is to a degree unrecognizable to themselves in a manner which becomes habituated.

The underpinning issue of all of these factors, and the ‘unfinished’ response to them, is a sense of loss of control. The individual who has suffered life trauma, and the resultant ‘shattering’ of their sense of self, no longer feels in control of their life and situation. One thing that can be controlled is their food intake, and in the case of folk who develop anorexia nervosa, they stop eating due to the desire either to control one factor in their existence which they can have complete control over, or actually do want to starve themselves to death, as a compensation or ‘way out’ of their current psychological ‘fragmentation’, and they stop eating as a way of enacting a prolonged suicide. For this reason (amongst several other reasons), folk with anorexia nervosa do not believe that they have an eating disorder, as by limiting their food intake, they feel that they are for the first time since whatever precipitated the development of the condition of anorexia nervosa, and are ‘controlling’ something in their own body, and it would be too psychologically draining for them to ‘lose’ what becomes in effect a control ‘mechanism’ that they feel completely ‘in control of’. At the same time, the individual may deny or ‘forget’ that they ever had any abuse or traumatic episode happen to them, as it is too threatening to their already damaged psyche to admit such, and as a mechanism of psychological denial, they ‘remove’ it from the conscious self to the nether world of their subconscious, where it continues to ‘trip them up’ and damage their lives until they confront it. So paradoxically, folk with anorexia nervosa can be all of completely out of control (from the context that they have been ‘ripped up’ psychologically by prior damaging events), in control (from the context of what they choose not to eat), and in some folk not aware of (due to protective psychological denial processes) their current physical state, sense of self, or underlying psychopathology. The distortions of body image, and dread of adding on even a pound of weight, are a result of these three ‘issues’ (amongst others) at play in their deep psyche and if this ‘lack of awareness’ is not addressed, the person with anorexia nervosa will literally starve themselves to death, as a method of maintaining control, or of negating the damage caused to them of whatever lead to the development of their condition. Therefore, in many cases, folk forget that anorexia nervosa can be a symptom of some deeper psychopathology, which may or not be ‘hidden’ from view, apart from it being a psychopathology in itself.

All of these ‘entangled issues’ make anorexia nervosa extremely difficult to treat. If folk deny that they are sick, it becomes very difficult to treat them, as whatever one does, they will not ‘stick with’ the treatment offered. Admitting that they are sick, or that they have a mental illness, requires them to acknowledge the psychological damage underpinning their anorexia nervosa (with anorexia nervosa being a symptom itself), and that they have no control over their life, and indeed that their own ‘treatment’ they have chosen to ‘cure’ their underlying psychopathology such as sexual abuse or other issue, namely not eating, or controlling their eating patterns to an extreme degree, has been wrong. A large number of folk with anorexia nervosa want to be left alone, and find it difficult to cope with being diagnosed as having anorexia nervosa due to the requirement this would make on them to confront their underlying psychopathology, and indeed, sadly, being diagnosed as suffering with anorexia nervosa creates a stigma of its own, and may ‘label’ and define them for life as such, and this is yet another psychological challenge to accept in their challenged state (that they have both an eating disorder and also underlying psychopathology) for the folk suffering from it. Treatment of the disorder involves trying to restore the person to a functional weight, treating the underlying psychological disorders that led to the development of anorexia nervosa, and reducing behaviors and activities that result from the disorder becoming habituated (such as not eating in front of other folk, hiding food, as well as of course not eating at all most of the time). Psychotherapy, cognitive behavioral therapy and family-based therapy have all been used with varying degrees of success to treat folk with the disorder. However, given that eating is a basic requirement of life, each day is an ordeal from the context that eating is required to happen in order for life to continue, and at each meal there is thus a conflict and habitual cycle of negation that is very difficult to alter or attenuate. Force feeding has been used in extreme conditions, but there are of course ethical issues associated with this, such as the individual’s rights, though of course the debate is whether folk with anorexia nervosa are in a ‘right’ state of mind and / or can make decisions that are good for themselves, rather than being damaging for themselves (similar issues of treatment occur in folk with alcoholism or who self-harm, amongst others). In the end, as described above, it is a disorder that is extremely challenging to manage, with a high level of chronic morbidity and mortality, very much as if the folk with the disorder ‘want to die’, as challenging as it is to describe it as such, or as a clinician to understand it as such.

Anorexia nervosa, for the reasons described above, is one of the most challenging disorders clinicians, friends and families of people that have the disorder have to manage and live with. To all of us watching the lady in the gym last week it was clearly obvious that she had a severe case of anorexia nervosa, yet she appeared oblivious to this, and was indeed working hard in the gym to ‘maintain fitness’ (thought of course in this case the exercise may be both a symptom and vehicle of psychopathology itself). In many ways society advocates restrictive eating and thinness, and from this perspective, the lady in this example would be congratulated for doing this to such extremes. Yet, paradoxically, someone like this who appears to be so in control, is actually completely out of control, and even more strangely, in many cases is not aware of it. The ‘mirror’ / self-image assessment function in their brains, however it works in both health and disease, appears to warp and become convex, and to the anorexic, their body image is usually so ‘fragmented’ that they see big where they are indeed thin. Even more sadly, as a clinician seeing folk like this makes one wonder what traumatic event the individual has gone through to trigger their anorexia nervosa, and whether they hopefully are in counselling to try and help them get to terms with whatever issue is causing their ongoing self-harm. Sadly thought, this is so difficult to do, as control mechanisms are involved which have become extreme, and make them unable to ‘move on’ from a life spent in the shadows to one in the light. Sigmund Freud suggested that folk have both a life instinct (Eros) and a death instinct (Thanatos), and one’s Thanatos instinct compels us humans to engage in risky and destructive behaviours that can lead to our own personal death. Clearly, in folk suffering from anorexia nervosa, a trigger has changed their ‘behavioral setting’ from Eros to Thanatos, and once changed, the God of Death appears to be fairly resistant to change. Much research is needed in the field to help us understand the psychopathology underlying anorexia nervosa better, and how to treat, or at least manage the condition. Mirror, mirror, on the wall, am I the thinnest person of them all may be the mantra of this disorder, but sadly the mirror is telling a lie. Each time I put in the two spoons of sugar which I enjoy my tea, I thank my parents for removing me from boarding school, before a fast of defiance became overwhelmed by Thanatos, the God of Death, and before I too went down to the place where everything which seems real is not, and where once one is over the edge of the abyss, there is very little chance of ever coming back. Dying by starving oneself to death may paradoxically represent a victory to the individual that pushes themselves to their own death, but the fight between Eros and Thanatos in a loved one, when Thanatos wins, is surely one of the most tragic things a clinician, family member or loved one can ever watch from a distance and understand, or even begin to comprehend, without wanting to smash the distorted mirror, and by doing so rebuild the fragmented spirit underneath it, no matter how impossible in real life this is.

The Self As Soliloquy – The Mind’s Inner Voices Make A Winner Or Loser Out Of You During Exercise And Competitive Sport

I was watching the highlights of an Australian Open warm-up tournament a few days ago, and noted how players often spoke aloud to themselves during the game, either congratulating themselves, or telling themselves to keep on going, or being critical of themselves when making an error. I have been trying to keep cycling through the Christmas break, even though it has been pretty cold and occasionally icy in the North-East UK, and I have had to have conversations with myself (internally, rather than out loud like the tennis players) both to get on the bike when sitting in front of a warm fire with a good book seemed a better option, and when I was out on the cycle path, and my toes and fingers felt frozen, to not stop, and keep on going. I have always been aware of the inner dialogue that continues incessantly in my mind throughout the day, either thinking of a science puzzle that I can’t work out, or how best to sort out a challenge at work, or being reminded by an inner voice to get presents for the family for Christmas, amongst a million other discussions I have with myself, and I am sure each of you reading this is aware of these inner voices similarly. Curiously, there has not been a lot of attention paid to inner dialogue or the inner voices, which is surprising given how central one’s inner dialogue is to one’s life, and are indeed a constant component of one’s life of which one is usually very aware of. Even less work has been done on the effect of inner voices, either positive or negative, on athletic performance (or indeed any type of performance, be it sport, work, or any activity which puts stress on one), or indeed if one’s inner voices alter during either competitive sport or exercise participation. A few years ago, I worked with one of the absolute legends and mavens in the Sport Science academic community, Professor Carl Foster, from Wisconsin in the USA, in order to try and understand a bit more about this curious yet fascinating subject, and we eventually published a theoretical review article on it a decade ago. All of these recent observations reminded me of this article we published, and the role of inner voices and the inner dialogue they create, and how this inner dialogue affects, and is altered by, competitive sporting activities and challenges.

Inner speech has also been described as self-talk, private speech, inner dialogue, soliloquy, egocentric speech, sub-vocal speech, and self-communicative speech, amongst others. Inner speech is predominantly overt during early childhood, and children up to four years of age believe that a mind of a person sitting quietly is ‘not doing anything’ and is ‘completely empty of all thoughts and ideas’. With increasing age, and associated increasing self-awareness, children reduce the quantity of overt inner speech, particularly when in large groups or around teachers, until overt inner speech only occurs when the child is alone, due to them becoming aware of the social consequences of unchecked overt inner speech. This change of inner speech from overt to covert appears to be related to appropriate physical and cognitive developmental changes, as children with Down’s syndrome continue to use overt inner speech, and folk who are Schizophrenic also use overt inner speech, and indeed feel that their inner speech is generated ‘outside’ of their heads and by an external agent, and often feel tormented by the ongoing dialogue which to them appears to be ‘outside’ of their minds. In adolescents, increasing negative or self-critical inner speech has been related to psychological disorders such as depression, anxiety and anger.

As described above, the makeup and function of the inner voices during sport have not been extensively researched previously. However, Van Raalte and colleagues examined overt inner speech in tennis players, and found that a large percentage was negative, and that there was a correlation between the quantity of negative inner speech and losing, which was not present between positive inner speech and winning, a somewhat puzzling finding. The laboratory group of father and son academics Lew and James Hardy have done some excellent work in this field. A study by their group, first authored by Kimberley Gammage, where they looked at the nature of inner speech in a variety of sports, found that 95% of athletes reported they used / were aware of inner speech during exercise (why 5% of folk do not is perhaps more curious than those folk that did), and noticed their inner speech to a greater degree when they were fatigued, when they wanted to terminate the exercise bout, and near the end of the exercise bout. Their inner speech was described most often to be phrases (such as ‘keep it up’ or ‘don’t stop’) rather than single words or sentences, and interestingly, they used the second person tense more frequently than the first person during exercise. The athletes perceived that they used inner speech for motivational purposes, maintaining drive and effort, maintaining focus and arousal, and to a lesser degree for cognitive functions such as ensuring correct race strategy, or using methods that would enhance their performance, such as breathing regularly. Helgo Schomer and colleagues did a great study where they got folk doing long Sunday runs to take walkie-talkies (the study was done in the 1980’s) and he would contact them randomly during the run and ask what they were thinking. While there will always be a degree of self-censorship of personal thoughts and inner discussion, he found that at lower running speeds, most inner speech was described as conversational chatter or problem solving social or work issues, and at higher speeds monitoring their body function, and the environment.

While all this work is excellent in describing what type of inner speech is ‘spoken’ at rest and during exercise, some of the best ‘deep’ theoretical work I have ever read in this field was generated by George Mead more than a hundred years ago, where he suggested that inner speech is a ‘soliloquy’ which occurs between at least two inner voices, rather than a single voice in one’s mind / brain. Mead defined these as an ‘I’ voice, representing the voice describing a current activity, or urging one to act, and a ‘Me’ voice, which takes the ‘perspective of the other’ and with which the ‘I’ voice is assessed. Mead also suggested that previous social interactions with other individuals allowed one to gain a viewpoint of oneself or one’s actions or thoughts, and therefore that ‘taking the perspective of the other’ is the ability to understand that another person’s viewpoint may be different to one’s own, and to use that opinion to change one’s own behaviour or viewpoint. Inner speech thus allows or creates the internalisation of this mechanism for taking another person’s perspective, as one can describe to a ‘real’ person (someone whom one has interacted with in the past that was significant to one), or an imagined person one has never previously interacted with, in one’s mind the reasons for behaving in a certain manner in a previous or ‘current’ situation, or how one is ‘feeling’ the effects of current activity, and the ‘Me’ voice takes the opinion of the other (and can be a conglomeration of many others, and be a ‘generalised other’) to assess the validity of how one says one is feeling. These concepts fit in well with the findings of Gammage and colleagues, who as described above, suggested that inner speech as mostly being reported as occurring in the second person tense (‘Me’), but with first person speech also occurring (which would be the ‘I’ voice), though why the ‘Me’ voice would be ‘heard’ more than the ‘I’ voice during exercise, if the findings of Gammage and colleagues occur in all athletes during all sporting events, is not clear.

A further fascinating hypothesis about inner speech was made by Morin and others, who suggested that inner speech was crucial for self-awareness (and one’s sense of self), by creating a time distance or ‘wedge’ between the ‘self’ and the mental or physical activities which the ‘self’ was currently experiencing. This time-wedge would enable retrospective analysis of the activity in which the individual was currently immersed in, thus facilitating the capacity for self-observation and thus both awareness of the ‘meaning’ of the activity and its effect on the individual, and self-awareness per se. In other words, if an individual was completely immersed in their current experience, they could not understand the meaning of the experience, because a time or perceptual gap is needed to create the time required to get enough ‘distance’ from the activity and assess and understand the meaning of an experience, and whether it is a threat to the individual if it continues. Inner speech therefore has been suggested to be the action that generates the time-wedge by creating a redundancy of self-information. This redundancy is the result of the difference between the actual physiological changes associated with the experience creating one unit of information about the event, and the descriptive ‘I’ inner speech creating a second (retrospective) unit of information of the same activity or event, separated from the first unit of information by a time-wedge. This time-wedge and redundancy of the same information allows retrospective comparison and analysis of the two different activities – the one in real time, and the other a retrospective copy, and a judgement is made of what is happening and how best to respond to it, by the ‘Me’ voice. This theory would suggest that all inner speech is retrospective, even the ‘I’ voice, and allows the retrospective analysis of an event in an ordered and structured way. Lonnie Athens, one of my all-time best creative thinkers, suggested 10 ‘rules’ that well describe all these complex inner speech processes described above: 1) People talk to themselves as if they are talking to someone else, except they talk in short hand; 2) When people talk to each other, they tell themselves at the same time what they are saying; 3) While people are talking to us, we have to tell ourselves what they are saying; 4) we always talk with an interlocutor when we soliloquise – the ‘phantom others’ (which is the ‘Me’ voice as described above); 5) The phantom community is the one and the many. However, we can normally only talk to one phantom at a time during our soliloquies; 6) Soliloquising transforms our raw, bodily sensations into perceived emotions. If it were not for our ability to soliloquise, we would not experience perceived emotions (like fatigue during exercise) in our existence. Instead, we wold only experience a steady stream of vague body sensations; 7) Our phantom others (the ‘Me’ voice) are the hidden sources of our perceived emotions. If we generate emotions by soliloquising about our body sensations, and if our phantom others play a critical role in our soliloquies, then our phantom other must largely shape the perceived emotion we generate; 8) Our phantom community (the ‘Me’ voice) occupies the centre stage of our life whether we are alone or with others. Talking to the phantom others about an experience we are undergoing is absolutely essential to understand its emergent meaning. Only in conversation with our phantom community do we determine its ultimate meaning; 9) Significant social experiences shape our phantom community (which are incorporated into our ‘Me’ voice); and 10) Given that some soliloquies are necessarily ‘multi-party’ dialogues, conflicts of opinion are always possible during inner speech soliloquies.

Relating all this fascinating theoretical work to an exercise bout therefore – as exercise continues, and physiological sensations change, these changes would be picked up by physiological sensors in the body and transferred to the brain, where they would be raised into our conscious mind by the ‘I’ voice, which already has a time-wedge to make sense of the raw feelings. Therefore, the athlete’s ‘I’ voice would say ‘I am tired’, and the ‘Me’ voice would respond to this assessment of the ‘I’ voice, based on their ‘perspective of the other’ viewpoint. The ‘Me’ Voice may be either positive in response (motivational – ‘keep going, the rewards will be worth it’) or negative (cognitive – ‘if you keep on going, you will damage yourself’). As the race or physical activity continued, as described above in the work of Kimberley Gammage and colleagues, athletes become more aware of their inner speech, probably because the symptoms of fatigue and distress described by the ‘I’ voice becomes more profound, and more persistent, and the ‘Me’ voice has to keep on responding to the more urgent and louder voice of the ‘I’ voice’, given that the ‘I’ voice is describing changes that have greater potential to be damaging to the athlete. It is likely that the relative input of each of the ‘I’ and ‘Me’ voices (and of course the subconscious processes that generate them) are either related to, or create, the temperament and personality of the individual, and their perception of success or failure in sport. For example, the ‘Me’ voice may suggest that it is not a problem to slow down when the ‘I’ voice indicates that the current speed the athlete is producing is too fast and may damage the athlete, if the familial, genetic or psychological history that created the ‘phantom others’ / ‘Me’ voice of the athlete perceived that winning sporting events to not be of particular importance. In contrast, the ‘Me’ voice may disagree with, and disapprove of, the desire of the ‘I’ voice to slow down, if the familial, genetic, psychological history of phantom others that make up the ‘Me’ voice believed that winning was very important, and slowing down a sign of personal failure and weakness. These relative viewpoints of the ‘Me’ voice will therefore likely shape the personality and self-esteem of the athlete (and indeed, all individuals), and whether they regard themselves a success or failure, if they try to keep on going and win, or try to keep on going and slow down due to having reached their physical body limits, which may not be congruent with the athletes psychological desires and demands. Furthermore, the ‘will’ of the athlete is probably to a large degree related to the forcefulness of the ‘Me’ voice in resisting the desire of the ‘I’ voice, or if the ‘I’ voice remains relatively silent even under times of duress or hardship, and is also likely created by the family history or genetic makeup of the athlete when creating the generalised phantom other / ‘Me’ voice. The relative input of both the ‘I’ and ‘Me’ components of an individual’s inner speech and the ‘viewpoint’ of the ‘Me’ voice may therefore be the link between the temperament and performance of an athlete, or may actually be part of or influence both.

In summary therefore, those tennis players with their overt inner speech (usually accompanied by fist pumping or smashed rackets depending on its positive or negative nature) open a window for us to understand one of the most potentially crucial and amazingly complex constituents of the perceptual loop of how sensations generated by the body under stress are changed into emotions that we ‘feel’ and respond to, which both explains to us how our body is feeling, behaving and ‘doing’ by the vocalisation of an ‘I’ voice, and at the same time creates our sense of self as a result of how the dialogue responds to this explanation, vocalised as inner speech, through our ‘Me’ voice, which is both reflective and created by the phantom others which shape us and regulate us. However, the inner voices can be our worst enemies, if they are too strong, or too harsh, or too demanding on us, and if so, they are probably produced by a damaged childhood with over-demanding parents, coaches, or teasing peer children which make us feel like what we are doing is never ‘enough’, even of course though what ‘enough’ is will always be a relative thing, and different for every different person on earth. Some Sport Psychologists have tried to improve sporting performance of athletes they work with by altering the content and nature of their inner speech, though Lonnie Athens made the relevant point that if one’s inner speech was too changeable, one’s sense of self would be fluid and not permanent, which in most folk it seems to be, and that only extreme psychological trauma, such as assault, divorce, near death or death of a loved one, where a state of existence is created which the ‘Me’ voice has no frame of reference, will allow the ‘Me’ voice be changed, and of course, it may change from a positive or neutral to a more negative ‘commentary state’. Having said that, my own inner voices have changed subtly as I have aged, and are (fortunately) more tolerant and forgiving as compared to what they were like in my youth. Often when doing sport, in contrast to when I was young when my ‘Me’ voice was insistent I keep going or be a failure, my inner voices now I am in my fifties often encourage me to slow down and look after myself, now that my body is old, less efficient, and damaged by the excesses of sport and wilful behaviour of my youth. So clearly there is some capacity to change and maintain one’s sense of self. Having said that, my sense of self is also subtly different from what it was in my youth, so this may be related to the changes in the make-up of my inner voices (and their underlying subconscious control mechanisms, perhaps due to the desires of my youth mostly being fulfilled in my life to date), or may not be related to them at all. More research work is needed for us to better understand all these concepts and mental activities that are continuously active in our mind and brain.

At this point in time our inner speech is the only real-time window we have into our subconscious, and is both ‘ourselves’ (as hard a concept this is to understand and accept) and our continuous companion through each minute of each day of our life. Often one wishes to turn off one’s inner voices, and interestingly some drugs do seem reduce the amount of ‘heard’ inner voices, but this does open up the philosophical challenge of whether if one has no inner speech, whether one will be aware that one is conscious, or aware of one’s current state of being. My inner voiced has been ‘shouting at me’ during the last two paragraphs of writing this, telling me I am tired and hungry, and it’s time to stop writing for the day and go in from my garden shed home working office to spend time with the family, and get some food and drink to replenish my energy levels. While I resisted their siren tune until completing this piece of writing, now it’s done, I will bow to my inner voices incessant request and sign off and head in for some welcome rest and relaxation. Of course I know that after a short period of relaxing, my inner speech will be chattering at me again, telling me to go back to my garden shed office and check the grammar and spelling of this article, and start preparing for the next. There is no peace for the wicked, particularly from our ever present, and ever demanding, inner voices!

Plato’s Horse And The Concept of Universals – Can You Have Life As We Know It Without Rules That Govern It

My young daughter’s precious Labrador puppy, Violet, has grown up, and recently turned two. As a family, we usually traditionally have Schnauzers as pets, and it’s been strange but nice to have a different breed around the home, and Labradors have great personalities. What struck me forcibly when Violet came in to our life, was that while she has a very different shape and form to our two Schnauzers, she is as instantly recognisable as a dog, as all our dogs are. It again struck me when the family watched a program on the most loved one hundred dog breeds in the UK (for those interested Labradors came in first), that while each of the different breeds had very different characteristics – think Chihuahua as compared to a Great Dane, or a Pug compared to a German Shepherd – they are were all instantly recognisable by our family members watching it, and I am sure just about all the folk who watched the program, as being dogs rather than cats, or lamas, or sheep. In the last few years of my academic career (and perhaps at a subconscious level for my entire research career), after having been an Integrative Control Systems scientist for most of my career, trying to understand how our different body systems and functions are controlled and maintained in an optimal and safe manner, I have come to understand, and have been exploring the concept, along with great collaborators Dr Jeroen Swart and Professor Ross Tucker, that perhaps general rules are operating across all body system control mechanisms, whatever their shape or form, and we recently published a theoretical research paper which described our thoughts. In my new role as Deputy Dean of Research at the University of Essex, I am fortunate to be working with the Department of Mathematics, helping them enhance their research from an organisational perspective, and it has been fascinating working with these supremely bright folk and seeing the work they do, and having it reiterated to me that even simple mathematical principles are abstract, and not grounded in anything in the physical world (for example knowing that 1 plus 2 equals 3 does not need any physical activity for it to be always true). All of these recent activities have got me thinking of the long pondered issue of universals, their relationship to rules and regulation governing and maintaining life, and which came first, the rules, or the physical activity that requires rules and regulation to be maintained in order for the physical activity to continue and be both organised and productive.

Universals are defined as a class of mind-independent (indeed human-independent) entities which are usually contrasted with individuals (also known as ‘particulars’ relative to ‘universals’), and which are believed to ‘ground’ and explain the relation of qualitative identity and resemblance among all individuals. More simply, they are defined as the nature or essence of a group of like objects described by a general term. For example, in the case of dogs described above, when we see a dog, whether it is a Labrador, Schnauzer, German Shepherd, or a myriad of other breeds, we ‘know’ it to be a dog, and the word dog is used to cover the ‘essence’ of all these and other breeds. Similarly, we know what a cat is, or a house, or shoes, despite each of these ‘types of things’ often looking very different to each other – there are clearly enough characteristics in each to define them by a universal defining name. Understanding universals gets even more complex though than merely thinking of them as being just a name or group of properties for a species or ‘type of thing’. Long ago, back in the time of antiquity, one of the first recorded philosophical debates was about universals, and whether they existed independently as abstract entities, or only as a term to define an object, species or ‘type of thing’. Plato suggested that a universal exists independent of that which they define, and are the true ‘things which we know’, even if they are intangible and immeasurable, with the living examples of them being copies and / or imitations of the universal, each varying slightly from the original universal, but bound in their form by the properties defined by the universal. In other words, he suggested that universals are the ‘maps’ of structures or forms which exist as we see and know them, for example a dog, or a horse, or a tree, and they exist in an intangible state somehow in the ‘ether’ around us, ‘directing’ the creation of the physical entities in some way which we have not determined or are currently capable of understanding.

In philosophical terms, this theory of universals as independent entities is known as Platonic Realism. After Plato came Aristotle, who felt that universals are ‘real entities’, like Plato perceived them to be, but in his theory (known as Aristotelian Realism), he suggested that universals did not exist independent of the particulars, or species, or ‘things’ they defined, and were linked to their physical existence, and would not exist without the physical entities they ‘represent’. In contrast to realism, Nominalism is a theory that developed after the work of these two geniuses (Nominalists are also sometimes described as Empiricists) which denied the existence of universals completely, and suggested that physical ‘things’, or particulars, shared only a name, and not qualities that defined them, and that universals were not necessary for the existence of species or ‘things’. Idealism (proposed by folk like Immanuel Kant) got around the problem of universals by suggesting that universals were not real, but rather were products of the minds of ‘rational individuals’, when thinking of that which they were looking at.

This dilemma of both the existence and nature of universals has to date not been solved, or adequately explained, given that it is impossible with current scientific techniques, or perhaps psychological ‘power’ in our minds, to be able to prove or disprove the presence of universals, and folk ‘believe’ in one of these different choices of universals depending on their world and life points of view. Religious folk would suggest that the world is created in God’s ‘image’, and to them God’s ‘images’ would be the universals from which all ‘God’s creatures’ are created. In contrast, with respect to evolution, which is diametrically opposed to the concept of religion, it is difficult to believe in both evolution and the presence of universals, as evolution is based on the concept of need and error-driven individual genetic changes over millennia in response to that need, which led to different species developing, and to the variety in nature and life we see all around us. In the evolutionary model therefore, the concept of universals (and the creation of the world by a God as posited by many religions) would appear to be counter-intuitive.

While a lot of debate has focused on ‘things one can see’ as the physical ‘particulars’ which are either a product of universals or not, there are more abstract activities which support the existence of universals independent of the mind or ‘things that they are involved with’. For example, the work done by Ross, Jeroen and myself developed from the realisation that a core principle of all physiological activity is homeostasis, which is defined as the maintenance by regulatory control processes or structures of physiological or physical activity within certain tolerable limits, in order to protect the individual or thing being regulated from being damaged, or damaging itself. Underpinning all homeostatic control mechanisms is the negative feedback loop, where when a substance or activity increases or decreases too much, initiates other activity as part of a circular control structure which has the capacity to act on the substance requiring control, and normalises or attenuates the changes, and keeps the activity or behaviour within required ‘safe levels’, which are set by homeostatic control mechanisms. The fascinating thing is that the same principle of negative feedback control loops occurs in all and any physical living system, and without it life could not occur. Whether gene activity, liver function, or whole body activity, all which have very different physical or metabolic regulatory structures and processes, all are controlled by negative feedback loop principles. Therefore, it is difficult not to perceive that the negative feedback loop is a type of universal, but one that works by similar ‘action’ across systems rather than ‘creating’ a physical thing in its likeness. Mathematics is another area in which folk believe universals are ‘at work’, given that even the simplest sums, such as one plus two equals three, needs no physical structure or ‘particular’ for them to always be such, and true. While we all use mathematical principles on a continuous basis, it is difficult to believe that such mathematical principles do not ‘exist’ in the absence of humans, or any physical shape or forms.

So where does all this leave us in understanding universals and their relevance to life as we know it? Perhaps what one’s viewpoint is regarding the existence of universals depends on one’s own particular epistemological perspective (understanding of the nature of knowledge and how it is related to one’s justified beliefs) and world view. Though I can in no way prove it, I believe in universals and would define myself as a Platonic Realist. This viewpoint comes from a career in science and working with exceptional scientists like Jeroen Swart and Ross Tucker getting to understand the exquisite and universal nature of control mechanisms which keep our bodies working the way which they do. However, I do not believe in any God or religion in any shape or form, and have greater faith in the evolutionary model, which is counter-intuitive relative to my belief in the presence of independent universals. Therefore, the potential similarities and differences between religion and universals, and evolution and universals described above is clearly redundant for my specific beliefs, and there is probably similar confusion in core beliefs for many (particularly research involved) folk. However, it is exciting to think (at least for me) that there may be universals out there that have no link to current activities or functions or species, and which may become evident to humans at some point in the future, by way of the development of new species or new ‘things’. Having said that, I guess it could be argued that if universals do not exist, progress and the evolution of ideas will lead us to new developments, species or ways of life in an evolution-driven, error-associated way. One cannot ‘see’ or ‘feel’ a negative feedback loop, or a maths algorithm, or universal for even something as simple as a dog, which is why perhaps to a lot of folk with a different epistemological viewpoint to mine it is challenging to accept the presence, or indeed the necessity, of and for universals. But when I look at our Labrador, and ‘know’ as such it is a dog as much as a Schnauzer, Chihuahua, or German Shepherd is, I feel sure there is the Universal dog out there somewhere in the ether that will perhaps keep my toes warm when I leave this world for the great wide void which may exist beyond it. And surely, given what a stunning breed they are, the Universal dog, if it exists out there, can only be a Labrador!

Homeostasis And The Constancy Principle – We Are All Creatures Of Comfort Even When We Go Out Of Our Comfort Zone

It is autumn in our part of the world, and the first chills are in the air in the late evening and early morning, and the family discussed last night the need to get out our warm clothes from storage in readiness for the approaching winter, in order to be well prepared for its arrival. After sharing in the fun of Easter Sunday yesterday and eating some chocolate eggs with the children, a persistent voice in my head this morning instructed me to eat less than normal today to ‘make up’ for this out of the normal chocolate eating yesterday. It is a beautiful sunny day outside as I write this, and I feel a strong ‘urge’ to stop writing and go out on a long cycle ride because of it, and have to ‘will’ these thoughts away and continue writing, which is my routine activity at this time of morning. After a recent health scare I have been checking on my own physical parameters with more care than normal, and found it interesting when checking what ‘normal’ values for healthy folk are, that most healthy folk have fairly similar values for things like blood glucose, blood pressure, cholesterol concentrations and other such parameters, and that there are fairly tight ranges of values of each of these which are considered normal and a sign of ‘health’, and if one’s values are outside of these, it is a sign of something wrong in the working of your body that needs to be treated and brought back into the normal range either by lifestyle changes, medication, or surgical procedures. All of these got me thinking about the regulatory processes that ensure that the body maintains its working ‘parts’ in a similar range in all folk, and the concept of homeostasis, which as a regulatory principle explains and underpins the maintenance of this ‘safe zone’ for our body’s multiple activities, including the sensing of any external or internal changes which could be associated with the potential for one of the variables to go out of the ‘safe zone’, and initiates changes either behaviourally or physiologically which attempt to bring the variable at risk back into the ‘safe zone’ either pre-emptively or reactively.

Homeostasis is defined scientifically as the tendency towards a relatively stable equilibrium between inter-dependent elements. The word was generated from the Greek concepts of ‘homiois’ (similar) and ‘stasis’ (standing still), creating the concept of ‘staying the same’. Put simply, homeostasis is the property of a system whereby it attempts to maintain itself in a stable, constant condition, and resists any changes or actions on the system which may change or destabilize the stable state. It’s origins as a concept were from the ancient Greeks, with Empedocles in around 400 BC suggesting that all matter consisted of elements which were in ‘dynamic opposition’ or ‘alliance’ with each other, and that balance or ‘harmony’ of all these elements was necessary for the survival of the individual or organism. Around the same time, Hippocrates suggested that health was a result of the ‘harmonious’ balance of the body’s elements, and illness due to ‘disharmony’ of the elements which it was made up of. Modern development of this concept was initiated by Claude Bernard in the 1870’s, who suggested that the stability of the body’s internal environment was ‘necessary for a free and independent life’ and that ‘external variations are at every instant compensated for and brought into balance’, and Walter Cannon in the 1920’s first formally called this concept of ‘staying the same’ homeostasis. Claude Bernard actually initially used the word ‘constancy’ rather than homeostasis to describe the concept, and interestingly, a lot of Sigmund Freud’s basic work on human psychology was based on the need for ‘constancy’ (though he did not cross-reference this more physiological / physical work and concepts), and that everyone’s basic needs were for psychological constancy or ‘peace’, and when one had an ‘itch to scratch’ one would do anything possible to remove the ‘itch’ (whether it be a new partner, a better house, an improved social status, or greater social dominance, amongst other potentially unrequited desires), and further that one’s ‘muscles are the conduit through which the ego imposes its will upon the world’. He and other psychologists of his era suggested that if an ‘itch’, urge or desire was not assuaged (and what causes these urges, whether a feeling of inadequacy, or previous trauma, or a desire for ‘wholeness’, is still controversial and still not clearly elicited even today), the individual would remain out of their required ‘zone of constancy’, and would feel negative emotions such as anxiety, irritation or anger until the urge or desire was relieved. If it was not relieved for a prolonged period this unrequited ‘itch’ could lead to the development of a complex, projection or psychological breakdown (such as depression, mania, anxiety, personality disorder or frank psychosis). Therefore, as much as there are physical homeostasis related requirements, there are potentially also similarly psychological homeostasis related requirements which are being reacted to by the brain and body on a continuous basis.

Any system operating using homeostatic principles (and all our body systems do so) has setpoint levels for whatever substance or process is being regulated in the system, and boundary conditions for the substance or process which are rigidly maintained and cannot be exceeded without a response occurring which would attempt to bring the activity or changes to the substance or process back to the predetermined setpoint levels or within the boundary conditions for them. The reasons for having these set boundary conditions are protective, in that if they were exceeded, the expectation would be the system would be damaged if the substance or process being regulated (for example, oxygen, glucose, sodium, temperature, cholesterol, or blood pressure, amongst a whole host of others) was used up too quickly or worked too hard, or was allowed to build up to toxic / extremely high levels or not used enough to produce life-supporting substrates or useable fuels, which would endanger the life and potential for continued activity of the system being monitored. For example, oxygen shortage results in death fairly quickly, as would glucose shortage, while glucose excess (known as diabetes) can also result in cellular and organ damage, and ultimately death if it is not controlled properly. In order for any system to maintain the substance or process within homeostasis-related acceptable limits, three regulatory factors (which are all components of what is known as a negative feedback loop) are required to be components of the system. The first is the presence of a sensory apparatus that can detect either changes in whatever substance or process is being monitored, or changes in the internal or external environment or other systems which interact with or impact on the substance or process being monitored. The second is a control structure or process which would be sent the information from the sensory apparatus, and would be able to make a decision regarding whether to respond to the information or to ignore it as not relevant. The third is an ‘effector’ mechanism or process which would receive commands from the control structure after it had made a decision to initiate a response in response to the sensed perturbation potentially affecting the system it controls, and make the changes to the system decided upon by the control structure in order to maintain or return the perturbed system to its setpoint value range.

The example of temperature regulation demonstrates both the complexity and beauty of homeostasis in regulating activity and protecting us on a continuous basis from harm. Physiological systems in most species of animals are particularly sensitive to changes in temperature and operate best in a relatively narrow ranges of temperature, although in some species a wider range of temperatures is tolerated. There are two broad mechanisms used by different organisms to control their internal temperature, namely ectothermic and endothermic regulation. Ectothermic temperature regulators (also known as ‘cold-blooded’ species), such as the frog, snake, and lizard, do not use many internal body processes to maintain temperature in the range which is acceptable for their survival, but rather use external, environmental heat sources to regulate their body temperature. If the temperature is colder, they will use the sun to heat themselves up, and if warm, they will look for shadier conditions. Ectotherms therefore have energy efficient mechanisms of maintaining temperature homeostasis, but are more susceptible to vagaries in environmental conditions compared to endotherms. In contrast, endotherms (also known as ‘warm-blooded’ species), into which classification humans fall, use internal body activity and functions to either generate heat in cold environments or reduce heat in warm conditions. In endotherms, if the external environment is too cold, and if the cold environment impacts on body temperature, temperature receptors measuring either surface skin temperature or core body temperature will send signals to the brain, which subsequently initiates a shiver response in the muscles, which increases metabolic rate and provides greater body warmth as a by-product of fuel / energy breakdown and use. If environmental temperature is too warm, of if skin or core temperature is too high, receptors will send signals to brain areas which initiates a chain of events involving different nerve and blood-related control processes which result in increased blood flow to the skin by vasodilatation, thereby increasing blood cooling capacity and sweat rate from the skin, thus producing cooling by water evaporation. All these endotherm associated heating and cooling processes utilize a large amount of energy, so from an energy perspective are not as efficient as that of ectotherms, but they do allow a greater independence from environmental fluctuations in temperature. It must be noted that endotherms also use similar behavioural techniques to ectotherms, such as moving into shady or cool environments if excessively hot, but as described above, can tolerate a greater range of environmental temperatures and conditions. Furthermore, humans are capable of ‘high level’ behavioural changes such as putting on or taking off clothes, in either a reactive or anticipatory way. It is evident therefore that for each variable being homeostatically monitored and managed (on a continuous basis) there are a complex array of responsive (and ‘higher-level’ pre-emptive) options available with which to counteract the potential or actual ‘movement’ of the variable beyond its ‘allowed’ metabolic setpoints and ranges.

There are a number of questions still to be answered regarding how homeostasis ‘works’ and how ‘decisions’ related to homeostasis occur. It is not clear how the regulatory mechanisms know which variable they ‘choose’ to defend as a priority. Brain oxygen would surely be the most important variable to ‘defend’, as would perhaps blood glucose levels, but how decisions are made and responses initiated for these variables preferentially, which may impact negatively on other systems with their own homeostatic requirements, is not clear. Furthermore, there is the capacity for ‘conflict’ between physical and psychological homeostatic mechanisms when homeostatic-related decisions are required to be made. For example, one’s ego may require one to run a marathon to fulfill a need to ‘show’ one’s peers that one is ‘tough’ by completing such a challenging goal, but doing so (running the marathon) creates major physical stress for and on the physical body. Indeed, some folk push themselves so hard during marathons that they collapse, even if they ‘feel’ warning signs of impending collapse, or of an impending heart attack, and choose to keep running despite these symptoms. To these folk, the psychological need to complete the event must be greater than the physical need to protect themselves from harm, and their regulatory decision-making processes clearly valences psychological homeostasis to be of greater importance than physiological homeostasis when deciding to continue exercising in the presence of such warning symptoms. However, running a marathon, while increasing physical risk of catastrophic physical events during the running of it, if done on a repetitive basis has positive physical benefits, such as weight loss and increased metabolic efficiency of the heart, lungs, muscles and other organ structures, along with enhanced psychological well-being which would be derived from achieving the set athletic performance-related goals. Therefore, ‘decision-making’ on an issue such as running a marathon is complex from a homeostasis perspective, with both short and long term potential benefits and harmful consequences. How these contradictory requirements and factors are ‘decided upon’ by the brain when attempting to maintain both psychological and physical homeostasis is still not clear.

A further challenge to homeostatic regulation is evident in the examples of when one has a fever, where a high temperature may paradoxically be beneficial, and after a heart attack, where an altered heart rate and blood pressure setpoint may be part of compensatory mechanisms to ensure the optimal function of a failing heart. While these altered values are potentially ‘outside’ of the ‘healthy’ setpoint level range, they may have utilitarian value and would be metabolically appropriate in relation to either a fever or failing heart. How the regulatory homeostatic control mechanisms ‘know’ that these altered metabolic setpoints are beneficial rather than harmful, and ‘accepts’ them as temporary or permanent new setpoints, or whether these altered values are associated with routine homeostatic corrective responses which are part of the body’s ongoing attempt to induce healing in the presence of fever or heart failure (amongst other homeostatically paradoxical examples), is still not clear. Whether homeostasis as a principle extends beyond merely controlling our body’s activity and behaviour, to more general societal or environmental control, is also still controversial. For example, James Lovelock, with his Gaia hypothesis, has suggested that the world in its entirety is regulated by homeostatic principles, and global temperature increases result in compensatory changes on the earth and in the atmosphere that lead to eventual cooling of the earth, and this warming and cooling continues in a cyclical manner – and most folk who believe in global warming as a contemporary unique catastrophic event don’t like this theory, even if it is difficult to support or refute without measuring temperature changes accurately over millennia.

Homeostatic control mechanisms can fail, and indeed our deaths are sometimes suggested to be the result of a failure of homeostasis. For example, cancer cells overwhelm cellular homeostatic protective mechanisms, or develop rapidly due to uncontrolled cellular proliferation of abnormal cells which are not inhibited by the regular cellular homeostatic negative feedback control mechanisms, which lead to physical damage to the body and ultimately our death, for these or other reasons that we are still not aware of. In contrast, Sigmund Freud, in his always contrary view of life, suggested as part of his Thanatos theory that death in the ultimate form of ‘rest’ and is our ‘baseline’ constancy-related resting state which we ‘go back to’ when dying (with suicide being a direct ‘mechanism’ of reaching this state in those whose psyche are operating too far away from their psychological setpoints, whatever these are), although again this is a difficult theory to either prove or disprove. Finally, what is challenging to a lot of folk about homeostasis from a control / regulatory perspective is that it is a conceptual ‘entity’ rather than a physical process that one can ‘show’ to be ‘real’, much like Plato’s Universals (to Plato the physical cow itself was less relevant than the ‘concept’ of a cow, and he suggested that one can only have ‘mere opinions’ of the former, while one has absolute knowledge of the latter, given the physical cow changes as it grows, ages, and dies, while the ‘concept’ of a cow is immutable and eternal). It is always difficult scientifically to provide categorical evidence which either refutes or support concepts such as universals and non-physical general control theories, even if they are concepts which appear to underpin all life as we know it, and without which function we could not exist in our current physical form and living environment.

As I look out the window at the falling autumn leaves and wonder whether we will have a very cold winter this year and whether we have prepared adequately for it clothes-wise (pre-emptive long-term homeostatic planning at its best, even if perhaps a bit ‘over-the-top’), while taking off my jersey as I write this given that the temperature has increased as the day has changed from morning to afternoon (surely a reactive homeostatic response), and as I ponder my health-related parameters, and work out how I am going to get those that need improvement as close to ‘normal’ as possible (surely as part of behavioural homeostatic / health-optimization planning), I look forward to that bike ride now I have managed to delay gratification of doing so until I have completed writing this (and feel a sense of well-being both from doing so and by realizing I am now ‘free’ to go on the ride and by doing so can remove the psychological ‘itch’ that makes me want to do it and therefore return to a state of psychological ‘constancy’ / homeostasis). Contemplating all of these, it is astonishing to think that all of what I, and pretty much all folk, do is underpinned by a desire to be, and maintain life, in a ‘comfort zone’ which feels right for me, and which is best for my bodily functions and psychological state. Given that all folk in the world have similar physical parameters when we measure them clinically, it is likely that our ‘comfort zones’ both physically and psychologically are not that different in the end. Perhaps the relative weighting which each of us assigns to our psychological or physical ‘needs’ create minor differences between us (and occasionally major differences such as in folk with psychopathology or with those who have significant lifestyle related physical disorders), though at the ‘heart of it all’, both psychologically and physically, is surely the over-arching principle of homeostasis. While on the bike this afternoon, I’ll ponder on the big questions related to homeostasis which still need to be answered, such as how homeostasis-related decisions are made, how the same principle can regulate not just our body, but also our behaviour, and perhaps that of societal and even planetary function, and how ‘universals’ originated and which came first, the physical entity or the universal. Sadly I think it will need a very long ride to solve these unanswered questions, and remove the ‘itch that needs scratching’ which arises from thinking of these concepts as a scientist who wants to solve them – and I don’t like to spend too long out of my comfort zone, which is multi-factorial and not purely bike-focused, but rather is part bike, part desk, part comfy chair, the latter of which will surely become more attractive after a few hours of cycling, and will ‘call me home’ to my next ‘comfort zone’, probably long before I can solve any of these complex issues while out on the ride watching the autumn leaves fall under a beautiful warm blue sky, with my winter cycling jacket unused but packed in my bike’s carrier bag in case of a change in the weather.

Contemporary Medical Training And Societal Medical Requirements – How Does One Balance The Manifest Need for General Practitioners With Modern Super-Specialist Trends

For all of my career, since starting as a medical student at the University of Cape Town as an 18 year old fresh out of school many years ago, I have been involved in the medical and health provision and training world, and have had a wonderful career first as a clinician, then as a research scientist, then in the last number of years managing and leading health science and medical school research and training. Because of this background and career, I have always pondered long and hard about what makes a good clinician, what is the best training to make a good clinician, how we define what a ‘good’ clinician is, and how we best align the skills of the clinicians we train with the needs and requirements of the country’s social and health environments in which they trained. A few weeks ago I had a health scare which was treated rapidly and successfully by a super-specialist cardiologist, and I was home the next day after the intervention, and ‘hale and hearty’ a few days after the procedure. If I had lived 50 years ago, and it had happened then, in the absence of modern high-tech equipment and the super-specialists skills, I would probably have died a slow and uncomfortable death treated with drugs of doubtful efficacy that would not have much benefited me much, let alone treat the condition I was suffering from. Conversely, despite my great respect for these super-specialist skills which helped me so successfully a few weeks ago, it has become increasingly obvious that this great success in clinical specialist training has come at the cost of reduced emphasis on general practitioner-focused training, and a reduction in the number of medical students choosing general practitioner work as a career after they qualify, which has caused problems both to clinical service delivery in a number of countries, particularly in rural areas of countries, and paradoxically put greater strain on specialist services despite their pre-eminence in contemporary clinical practice in most countries around the world. My own experience with grappling with this problem of how to increase general practitioners as an outcome of our training programs, as a Head of School of Medicine previously, and this recent health scare which was treated so successfully by super-specialist intervention, got me thinking of how best we can manage the contradictory requirements of the need for both general practitioners and specialists in contemporary society, and whether this conundrum should be best managed by medical schools, health and hospital management boards, or government-led strategic development planning initiatives.

It is perhaps not surprising, given the exponential development of technological innovations that originated in the industrial revolution and which changed how we live, that medical work also changed and became more technologically focused, which in turn required both increased time and increased specialization of clinical training to utilize these developing technologies, such as surgical, radiology investigative and laboratory-based diagnostic techniques. The hospital (Groote Schuur) and medical school (University of Cape Town) where I was trained was famous for the achievements of Professor Chris Barnard and his team’s work performing the first heart transplant there, using a host of advanced surgical techniques, heart-lung machines to keep the patients alive without a heart for a brief period of time, and state-of-the-art immunotherapy techniques to resist heart rejection, all specialist techniques he and his team took many years to master in some great medical schools and hospitals in the USA. Perhaps in part because of this, our training was very ‘high-tech’, consisting of early years spent learning basic anatomy, physiology and pathology-based science, and then later years spent in surgical, medical, and other clinical specialty wards, mostly watching and learning from observation of clinical specialists going about their business treating patients. If I remember it correctly, there were only a few weeks of community-based clinical educational learning, very little integrative ‘holistic’ patient-based learning, and almost no ‘soft-skill’ training, such as optimal communication with patients, working as part of a team with other health care workers such as nurses and physiotherapists, or learning to help patients in their daily home environment and social infrastructure. There was also almost no training whatsoever in the benefits of ‘exercise as medicine’, or of the concept of wellness (where one focuses on keeping folk healthy before they get ill, rather than dealing with the consequences of illness). This type of ‘specialist-focused’ training was common, particularly in Western countries, for most of the last fifty or so years, and as a typical product of this specialist training system, for example, I chose first clinical research and then basic research rather than more patient-focused work as my career choice, and a number of my colleagues from my University of Cape Town medical training class of 1990 have had superb careers as super-specialists in top clinical institutions and hospitals all around the world.

This increasing specialization of clinical training and practice, such as the example of my own medical training described above, has unfortunately had a negative impact both on general practitioner numbers and primary care capacity. A general practitioner (GP) is defined as a medical doctor who treats acute and chronic illnesses and provides preventative care and health education to patients, and who has a holistic approach to clinical practice that takes all of biological, social and psychological factors into consideration when treating patients. Primary care is defined as the day-to-day healthcare of patients and communities, with the primary care providers (GP’s, nurses, health associates or social workers, amongst others) usually being the first contact point for patients, referring patients on to specialist care (in secondary or tertiary care hospitals), and coordinating and managing the long term treatment of patient health after discharge from either secondary or tertiary care if it is needed. In the ‘old days’, GP’s used to work in their community often where they were born and raised, worked 24 hours a day as needed, and maintained their relationship with their patients through most or all of their lives. Unfortunately, for a variety of reasons, GP work has changed, and they now often work set hours, patients are rotated through different GP’s in a practice, and the number of graduating doctors choosing to be GP’s is diminishing, and there is an increasing shortage of GP’s in communities and particularly rural areas of most countries as a result. Sadly, GP work is often regarded as being of lower prestige than specialist work, the pay for GP’s has often been lower than that of specialists, and with the decreased absolute number of GPs, the work burden on many GP’s has increased (and paradoxically with computers and electronic facilities the note and recording taking requirements of GP’s appears to have increased rather than decreased) leading to increased level of burnout and GP’s choosing to turn to other clinical roles or to leave the medical profession completely, which exacerbates the GP shortage problem in a circular manner. Training of GP’s has also evolved into specialty-type training, with doctors having to spend 3-5 years ‘specializing’ as a GP (often today called Family Practitioners or Community Health Doctors), and this also has paradoxically potentially put folk off a GP career, and lengthens the time required before folk intent on becoming GP’s can do so and become board certified / capable of entering or starting a clinical GP practice. As the number of GP’s decrease, it means more folk go directly to hospital casualties as their first ‘port of call’ when ill, and this puts a greater burden on hospitals, which somewhat ironically also creates an increased burden on specialists, who mostly work in such hospitals, and who end up seeing more of these folk who could often be treated very capably by GP’s. This paradoxically allows specialists less time to do the specialist and super-specialist roles they spent so many years training for, with the result that waiting list and times for ‘cold’ (non-emergency) cases increases, and hospital patient care suffers due to patient volume overload.

At a number of levels of strategic management of medical training and physician supply planning, there have been moves to counter this super-specialist focus of training and to encourage folk to consider GP training as an appealing career option. The Royal College of Physicians and Surgeons of Canada produced a strategic clinical training document (known as the ‘CanMeds’ training charter) which emphasizes that rather than just training pure clinical skills, contemporary training of clinical doctors should aim to create graduates who are all of medical experts, communicators, collaborators, managers, health advocates, scholars and professionals – in other words a far more ‘gestalt’ and ‘holistically’ trained medical graduate. This CanMeds document has created ‘waves’ in the medical training community, and is now used by many medical schools around the world now as their training ‘template’. Timothy Smith, senior staff writer for the American Medical Association, published an interesting article recently where he suggested that similar changes were occurring in the top medical schools in the USA, with clinical training including earlier exposure to patient care, more focus on health systems and sciences (including wellness and ‘exercise is medicine’ programs), shorter time to training completion and increased emphasis on using new communication technologies more effectively as part of training. In my last role as Head of the School of Medicine at the University of the Free State, working with Faculty Dean Professor Gert Van Zyl, Medical Program Director Dr Lynette Van Der Merwe, Head of Family Medicine Professor Nathanial Mofolo, Professor Hanneke Brits, Dr Dirk Hagemeister, and a host of other great clinicians and administrators working at the University or the Free State Department of Health, the focus on the training program was shifted to try to include a greater degree of community based education as a ‘spine’ of training rather than as a two week block in isolation, along with a greater degree of inter-professional education (working with nurses, physiotherapists, and other allied health workers in teams as part of training to learn to treat a patient in their ‘entirety’ rather than as just a single clinical ‘problem’), and an increased training of ‘soft skills’ that would assist medical graduates not only with optimal long term patient care, but also with skills such as financial and business management capacity so that they would be able to run practices optimally, or at least know when to call in experts to assist them with non-clinical work requirements, amongst a host of other innovative changes. We, like many other Universities, also realized that it was important to try and recruit medical students from the local communities around the medical school in which they grew up, and to encourage as many of these locally based students as possible to apply for medical training, though of course selection of medical students is always a ‘hornets nest’, and it is very challenging to get it right balancing marks, essential skills and community needs of the many thousands of aspirant clinicians who wish to do medicine when so few places are available to offer them.

All of these medical training initiatives to try and initiate changes of what has become a potentially ‘skewed’ training system, as described above, are of course ‘straw in the wind’ without government backing and good strategic planning and communication by country-wide health boards, medical professional councils, and hospital administrators who manage staffing appointments and recruitment. As much as one needs to change the ‘focus’ and skills of medical graduates, the health structures of a country need to be similarly changed to be ‘focused’ on community needs and requirements, and aligned with the medical training program initiatives, for the changes to be beneficial and to succeed. Such training program changes and community based intervention initiatives have substantial associated costs which need to be funded, and therefore there is a large political component to both clinical training and health provision. In order to strategically improve the status quo, governments can choose to either encourage existing medical schools to increase student numbers and encourage statutory clinical training bodies to enact changes to the required medical curriculum to make it more GP focused, or build more medical schools to generate a greater number of potential GP’s. They can also pay GP’s higher salaries, particularly if they work in rural communities, or ensure better conditions of service and increased numbers of allied health practitioners and health assistants to lighten the stress placed on GP’s, in order to ensure that optimal community clinical facilities and health care provision is provided for. But, how this is enacted is always challenging, given that different political parties usually have different visions and strategies for health, and changes occur each time a new political party is elected, which often ‘hinders’ rather than ‘enacts’ required health-related legislation, or as in the case of contemporary USA politics, attempts to rescind previous change related healthcare acts if they were enacted by an opposition political party. There is also competition between Universities which have medical schools for increases in medical places in their programs (which result in more funding flowing in to the Universities if they take more students) and of course any University that wishes to open a new medical school (as my current employers, the University of Waikato wish too, and who have developed an exciting new community focused medical school strategic plan that fulfills all the criteria of what a contemporary focused GP training program should be, that will surely become an exemplary new medical school if their plan is approved by the government) is regarded as a competition for resources by those Universities who already run medical training programs and medical schools. Because of these competition-related and political issues, many major health-related change initiatives for both medical training programs and the related community and state structural training requirements are extremely challenging to enact, and are why so many planned changes become ‘bogged down’ by factional lobbying either before they start or when they are being enacted. This is often disastrous for health provision and training, as chaos ensues when a ‘half-changed’ system becomes ‘stuck’ or a new political regime or health authority attempts to impose further, often ‘half-baked’ changes on the already ‘half-changed’ system, which results in an almost unmanageable ‘mess’ which is sadly often the state of many countries medical training, physician supply, and health facilities, to the detriment both of patients and communities which they are meant to serve and support.

The way forward for clinical medical training and physician supply is therefore complex and fraught with challenges. But, having said this, it is clear that changes are needed, and brave folk with visionary thinking and strategic planning capacity are required to both create sound plans that integrate all the required changes across multiple sectors that are needed for the medical training changes to be able to occur, and to enact them in the presence of opposition and resistance, which is always the case in the highly politicized world of health and medical training. Two good examples of success stories in this field were the changes to the USA health and medical training system which occurred as a result of the Flexner report of 1910, which set out guidelines for medical training throughout the USA, which were actually enacted and came to fruition, and the development of the NHS system in the UK in the late 1940’s, which occurred as a result of the Beveridge report of 1942, which laid out how and why comprehensive, universal and free medical services were required in the UK, and how these were to be created and managed, and these recommendations were enacted by Clement Attlee, Aneurin Bevin and other members of the Labour government of that time. Both systems worked for a time, but sadly both in the USA and UK, due to multiple reasons and perhaps natural system entropy, both of these countries health services are currently in a state of relative ‘disrepair’, and it is obvious that major changes to them are again needed, and perhaps an entire fresh approach to healthcare provision and training similar to that initiated by the Flexner and Beveridge reports are required. However, it is challenging to see this happening in contemporary times with the polarized political status currently occurring in both countries, and strong and brave health leadership is surely required at this point in time in these countries, as always, in order to initiate the substantial strategic requirements which are required to either ‘fix’ each system or create an entirely new model of health provision and training. Each country in the world has different health provision models and medical training systems, which work with varying degrees of success. Cuba is an example of one country that has enacted wholesale GP training and community medicine as the centerpiece of both their training and health provision, though some folk would argue that they have gone too far in this regard in their training, as specialist provision and access is almost non-existent there. Therein lies an important ‘rub’ – clearly there is a need for more GP and community focused medical training. But equally, it is surely important that there is still a strong ‘flow’ of specialists and super-specialists to both train the GP’s in the specific skills of each different discipline of medicine, and to treat those diseases and disorders which require specialist-level technical skills. My own recent health scare exemplifies the ‘yin and yang’ of these conflicting but mutually beneficial / synergistic requirements. If it were not for the presence of a super-specialist with exceptional technical skills, I might not be alive today. Equally the first person I phoned when I noted concerning symptoms was not a super-specialist, but rather was my old friend and highly skilled GP colleague from my medical training days, Dr Chris Douie, who lives close by to us and who responded to my request for assistance immediately. Chris got the diagnosis spot on, recommended the exact appropriate intervention, and sent me on to the required super-specialist, and was there for me not just to give me a clinical diagnosis but also to provide pastoral care – in other words ‘hold my hand’ and show me the empathy that is so needed by any person when they have an unexpected medical crisis. In short, Chris was brilliant in everything he did as first ‘port of call’, and while I eventually required super-specialist treatment of the actual condition, in his role as GP (and friend) he provided that vital first phase support and diagnosis, and non-clinical empathic support, which is so needed by folk when they are ill (indeed historically the local GP was not just everyone’s doctor but also often their friend). My own example therefore emphasizes this dual requirement for both GP and specialist health provision and capacity.

Like most things, medical training and health care provision has like a pendulum ‘swung’ between specialist and generalist requirements and pressures in the last century. The contemporary perception, in an almost ‘back to the future’ way, is that we have perhaps become too focused on high technology clinical skills and training (though as above there will always be a place and need for these), and we need more of our doctors to be trained to be like their predecessors of many years ago, working out in the community, caring for their patients and creating an enduring life-long relationship with them, and dealing with their problems early and effectively before they become life-threatening and costly to treat and requiring the intervention of expensive specialist care. It’s an exciting period of potential world-wide changes in medical training and the clinical health provision to communities, and a great time to be involved in either developing the strategy for medical training and health provision and / or enacting it – if the folk involved in doing so are left in peace by the lobby groups, politicians and folk who want to maintain the current unbalanced status quo due to their own self-serving interests. Who knows, maybe even clinicians, like in the old days, will be paid again by their patients with a chicken, or a loaf of freshly baked bread, and goodwill will again be the bond between the community, the folk who live in them, and the doctors and healthcare workers that treat them. And for my old GP friend Chris Douie, who is surely the absolute positive example and role model of the type of doctor we need to be training, a chicken will heading his way soon from me, in lieu of payment for potentially saving my life, and for doing so in such a kind and empathetic way, as surely any GP worth his or her ‘salt’ would and should do!

Muscle Dysmorphia And The Adonis Complex – Mirror, Mirror On The Wall, Why Am I Not The Biggest Of Them All

I have noticed recently that my wonderful son Luke, who is in the pre-teenage years, has become more ‘aware’ of his body and discusses things like ‘six-pack abs’ and the need to be strong and have big muscles, probably like most boys of his age. I remember an old colleague at the University of Free State mention to me that her son, who was starting his last year at school, and who was a naturally good sports-person, had started supplementing his sport with gym work as he perceived that ‘all boys his age were interested in having big muscles’, as my colleague described it. A few decades ago, my old colleague and friend Mike Lambert, exercise physiologist and scientist without peer, and I did some work researching the effect of anabolic steroid use on bodybuilders, and noted that there were not just physical but also psychological changes in some of the trial participants. I did a fair amount of time in the gym in my University days, and always wondered why some of the biggest folk in the gym seemed to do their workouts with long pants and tracksuit tops, sometimes with hoods up, even on hot days, and how in conversation with them I was often told that despite them being enormous (muscular rather than obese-wise), they felt that they were small compared to their fellow bodybuilders and weightlifters, and that they needed to work harder and longer in the gym than they were currently doing to get results. All of these got me thinking of the fascinating syndrome known as muscle dysmorphia, also known as the Adonis complex, ‘bigorexia’, or ‘reverse anorexia’ and what causes the syndrome / disorder in the folk that develop it.

Muscle dysmorphia is a disorder mostly affecting males (though females can also be affected) where there is a belief or delusion that one’s body is too small, thin, insufficiently muscular or lean, despite it often being normal or exceptionally large and muscular, and related to obsessional efforts to increase muscularity and muscle mass by weightlifting exercise routines, dietary regimens and supplements, and often anabolic steroid use. This perception of being not muscular enough becomes severely distressing for the folk suffering from the syndrome, and the desire to enhance their muscularity eventually impacts negatively on the sufferer’s daily life, work and social interactions. The symptoms usually begin in early adulthood, and are most prevalent in body-builders, weight-lifters, and strength-based sports participants (up to 50 percent in some bodybuilder population studies, for example). Worryingly, muscle dysmorphia is increasingly being diagnosed in younger / adolescent folks, and across the spectrum of sports participants, and even in young folk who begin lifting weights for aesthetic rather than sport-specific purposes, and who from the start perceive they need to go to gym to improve their ‘body beautiful’. Two old academic friends of mine, Dave Tod and David Lavallee, published an excellent article on muscle dysmorphia a few years ago, where they suggested that the diagnostic criteria for the disorder are that the sufferer needs to be pre-occupied with the notion that their bodies are insufficiently lean and muscular, and that the preoccupation needs to cause distress or impairment in social or occupational function, including at least two of the four following criteria: 1) they give up / excuse themselves from social, occupational or recreational activities because of the need to maintain workout and diet schedules; 2) they avoid situations where their bodies may be exposed to others, or ‘endure’ such situations with distress or anxiety; 3) their concerns about their body cause distress or impairment in social, occupational or other areas of their daily functioning; and 4) they continue to exercise and monitor their diet excessively, or use physique-enhancing supplements or drugs such as anabolic steroids, despite knowledge of potential adverse physical or psychological consequences of these activities. Folk with muscle dysmorphia spend a lot of their time agonizing over their ‘situation’, even if it is in their mind rather than reality, look at their physiques in the mirror often, and are always of the feeling that they are smaller or weaker than what they really are, so there is clearly some cognitive dissonance / body image problem occurring in them.

What causes muscle dysmorphia is still not completely known, but what is telling is that it was first observed as a disorder in the late 1980’s and early 1990’s, and was first defined as such by Harrison Pope, Katharine Phillips, Roberto Olivardia and colleagues in a seminal publication of their work on it in 1997. There are no known reports of this disorder from earlier times, and as suggested by these academics, it’s increasing development appears to be related a growing social obsession with ‘maleness’ and muscularity, that is evident in the media and marketing adverts of and for the ‘ideal’ male in the last few decades. While women have had relentless pressure on them from the concept of increasing ‘thinness’ as the ‘ideal body’ perspective for perhaps a century or longer from a social media perspective, with for example the body size of female models and advertised clothes sizes decreasing over the years (and it has been suggested that in part this is responsible for the increase in the prevalence in anorexia nervosa in females), it appears that males are now under the same marketing / media ‘spotlight’, but more from a muscularity rather than a ‘thinness’ perspective, with magazines, newspapers and social media often ‘punting’ this muscular ‘body ideal’ for males when selling male-targeted health and beauty products. Some interesting changes have occurred which appear to support this concept, for example the physique of GI-Joe toys for young boys changing completely in the last few decades, apparently being much more muscular in the last decade or two compared to their 1970 prototypes. Matching this change, in 1972 only 15-20 percent of young men disliked their body image, while in 2000 approximately 50% percent of young men disliked their body image. Contemporary young men (though older men may also be becoming increasingly ‘caught up’ in similar desire for muscularity as contemporary culture puts a price on the ‘body beautiful’ right through the life cycle) perceive that they would like to have 13 kg more muscle mass on average, and believe that women would prefer them to have 14 kg more muscle mass to be most desirable, though interestingly when women were asked about this, women were happy with the current mass of their partners, and many were indeed not attracted to heavily-muscled males. Therefore, it appears that social pressure may play a large part in creating an environment where men perceive their bodies in a negative light, and this may in turn lead to the development of a ‘full blown’ muscle dysmorphia syndrome in some folk.

While the concept that social pressure plays a big role in the development of muscle dysmorphia, other factors have also been suggested to play a part. Muscle dysmorphia is suggested to be associated with, or indeed a sub-type of, the more general body dysmorphic disorder (and anorexia nervosa, though of course anorexia nervosa is about weight loss, rather than weight gain), where folk develop a pathological dislike of one or several body parts or components of their appearance, and develop a preoccupation with hiding or attempting to fix their perceived body flaw, often with cosmetic surgery (and this apparently affects up to 3 percent of the population). It has been suggested that both muscle dysmorphia and body dysmorphic disorder may be caused by a problem of ‘somatoperception’ (knowing one’s own body), which may be related to organic lesions or processing issues in the right parietal lobe of the brain, which is suggested to be the important area of the brain for own-body perception and the sense of self. In folk that have lesions of the right parietal cortex, they perceive themselves to be ‘outside’ of their body (autoscopy), or that body parts are missing / there is a lack of awareness of the existence of parts of the body (asomatognosia). Non-organic / psychological factors have also been associated with muscle dysmorphia, apart from media and socio-cultural influences, including being a victim of childhood bullying, being teased about levels of muscularity when young, or being exposed to violence in their family environment. It has also been suggested that it is associated with appearance-based rejection sensitivity, which is defined as anxiety-causing expectations of social rejection based on physical appearance – in other words, for some reason, folk with muscle dysmorphia are anxious that they will be socially rejected due to their perceived lack of muscularity and associated appearance deficits. Whether this rejection sensitivity is due to prior negative social interactions, or episodes of childhood teasing or body shaming, has not been well elicited. Interestingly, while studies have reported inconclusive correlations with body mass index, body fat, height, weight, and pubertal development age, there have been strong correlations reported with mood disorders, anxiety disorders, perfectionism, substance abuse, and eating and exercise-dependence / addiction disorders, as well as with the clinical depression, anxiety, and obsessive-compulsive disorders. There does not appear to be a strong relationship to narcissism, which perhaps is surprising. Whether these are co-morbidities or they have a common pathophysiology at either a psychological or organic level is yet to be determined. It has been suggested that a combination of cognitive behavioural therapy and selective serotonin reuptake inhibitor prescription (a type of antidepressant) may improve the symptoms of muscle dysmorphia. While these treatment modalities would support a link between muscle dysmorphia and the psychological disorders described above, the efficacy of these treatment choices is still controversial, and there is unfortunately a high relapse rate. It is unfortunately a difficult disorder to ‘cure’, given that all folk need to eat regularly in order to live, and most folk incorporate exercise into their daily routines, which make managing ‘enough’ but not ‘excessive’ amounts of weightlifting and dietary regulation difficult to regulate in folk who have a disordered body image.

Muscle dysmorphia appears therefore to be a growing issue in contemporary society, which is increasing in tandem with the increased media-related marketing drive for the male ‘body beautiful’, which now appears to be operating at a similar level to the ‘drive for thinness’ media marketing which has blighted the female perception of body image for a long time, and has potentially led to an increased incidence of body image disorders such as anorexia nervosa and body dysmorphic syndrome. However none of these are gender specific, and it is not clear how much of a relationship these body image disorders have with either organic brain or clinical psychological disorders, as described above. It appears to be a problem mostly in young folk, with older folk being more accepting of their body abnormalities and imperfections, whether these are perceived or real, though sadly it appears that there is a growing incidence of muscle dysmorphia and other body image disorder in older age, as societies relationship and expectations of ‘old age’ changes. As I see my son become more ‘interested’ in his own physique and physical development, which must have obviously been caused by either discussions with his friends, or due to what he reads, or what the ‘actors’ in his computer games look like which he so enjoys playing, like all his friends, I hope he (and likewise my daughter) will always enjoy his sport but have a healthy self-image through the testing teenage and early adult period of time. I remember those bodybuilders my colleague Mike and I worked with all those years ago, and how some of them were comfortable with their large physiques, while with some it was clearly an ordeal to take off their shirts in order to be tested in the lab as part of the trials we did back then. The mind is very sensitive to suggestion, and it is fascinating to see that males now are being ‘barraged’ with advertising suggesting they are not good enough, and if they buy a certain product it will make them stronger, fitter, better, and thus more attractive, to perhaps the same level females have been subjected to for a long period of time. The mind is also sensitive to bullying, teasing and body shaming, as well as a host of other social issues which impinge on it particularly in its childhood and early adolescent development phases. It’s difficult to know where this issue will ‘end’, and whether governmental organizations will ‘crack down’ on such marketing and media hype which surely ‘target’ folks (usually perceived) physical inadequacies or desires, or if it is too late to do so and such media activity has become innate and part of the intrinsic fabric of our daily life and social experience. Perhaps education programs are the way to go at school level, though these are unfortunately often not successful.

There are so many daily challenges one has to deal with, it may seem almost bizarre that folk can spend time worrying about issues that are not even potentially ‘real’, but for the folk staring obsessively at themselves in the mirror, or struggling to stop the intrusive thoughts about their perceived physical shortcomings, these challenges are surely very real, and surely all-consuming and often overwhelming. In Greek mythology Adonis was a well-muscled half man, half god, whose was considered to be the ultimate in masculine beauty, and according to mythology his masculine beauty was so great that he won the love of Aphrodite, the queen of all the gods, because of it. Sadly for the folk with muscle dysmorphia, while they may be chasing this ideal, they are likely to be too busy working on creating their own perfect physique to have time to ‘woo’ their own Aphrodite, and indeed, contemporary Aphrodite’s don’t appear to even appreciate the level of muscularity they eventually obtain. The mirror on the wall, as it usually is, is a false siren, beckoning those weak enough to fall into its thrall – no matter how big, never to appear as the biggest or most beautiful of all.

Consistency Of Task Outcome And The Degrees Of Freedom Problem-The Brain Is Potentially Not A Micro-Manager When Providing Solutions To Complex Problems

Part of the reason I enjoy cycling as my chosen sport now I am older is not just because it is beneficial from a health perspective, but because the apparent regularity of the rhythmical circular movement required for pedalling creates a sense of peace in me and paradoxically allows my mind to wander a bit away from its routine and usually work-focussed and life task orientated thoughts. I enjoy watching competitive darts, from the perspective of marvelling at how the folk participating in the competitions seem to so often hit the small area of the board they are aiming for with such precision, after fairly rapidly throwing their darts when it is their turn to do so. This week an old colleague and friend from University of Cape Town days, Dr Angus Hunter, published some interesting work on how the brain controls muscle activity during different experimental conditions, a field of which he is a world expert in, and it was great to read about his new research and innovative ideas as always. Some of the most fun times of my research career were spent in the laboratory working with Angus measuring muscle activity during movement related tasks, where one of our most challenging issues to deal with was the variability of the signal our testing devices recorded when measuring either the power output from, or electrical activity in, muscle fibres each time they contracted when a trial participant was asked to do the same task. A large part of the issue we had to solve then was whether this was signal ‘noise’ and an artefact of our testing procedures, or if it was part of the actual recruitment strategy the brain used to control the power output from the muscles. All of these got me thinking about motor control mechanisms, and how movement and activity is regulated in a way that gets tasks done in a seemingly smooth and co-ordinated way, often without us having to think about what we are doing, while when one measures individual muscle function it is actually very ‘noisy’ and variable, even during tasks which are performed with a high degree of accuracy, and how the brain either creates or ‘manages’ this variability and ‘noise’ to generate smooth and accurate rhythmical or target-focussed activity, as that which occurs when cycling and throwing darts respectively.

Some of the most interesting scientific work that I have ever read about was done by Nikolai Bernstein, a Russian neurophysiologist, who when working in the 1920’s at the somewhat euphemistically named Moscow Central Institute of Labour, examined motor control mechanisms during movement. As part of the communist government of the times centrally driven plans to improve worker productivity and output, Bernstein did research on manual labour tasks such as hammering and cutting, in order to try and understand how to optimise it. Using novel ‘cyclogram’ photography techniques, where multiple pictures were taken of a worker using a hammer or chisel to which a light source had been attached, he was able to produce the astonishing observation that each time the worker hit a nail or cut through metal, their arm movements were not identical each time they performed the action, and rather that there was a great degree of variability each time the similar action was performed, even though usually this variability in action produced an outcome which had a high degree of accuracy. He realized that each complete movement, such as moving the arm towards the target, is made up of a number of smaller movements of muscles around the shoulder, elbow and wrist joints, which together synergistically create the overall movement. Given how many muscles there are in the arm, working around three joints (and potentially more when one thinks of the finger joints and muscles controlling them), he suggested that were a very large number of potential combinations of muscle actions and joint positions that could be used for the same required action, and a different combination of these appeared to be ‘chosen’ by the brain each time it performed a repetitive task. From a motor control perspective, Bernstein deduced that this could potentially cause a problem for the brain, and whatever decision-making process decided on which movement pattern it would use to complete a task, given that it created a requirement for choosing a particular set of muscle synergies from a huge number of different options available, or in contrast not choosing all the other muscle synergistic options, each time the individual was required to perform a single task or continue performing a repetitive task. This would require a great amount of calculation and decision-making capacity on a repetitive basis by the brain / control processes, and he called this the motor redundancy, or degrees of freedom, problem.

Like a lot of work performed in the Stalin era in Russia, his fascinating work and observations did not become known to Western scientists until the 1960’s, when he published a text-book of his career in science, which was subsequently translated and taken forward by excellent contemporary movement control scientists like Mark Latash of the University of Pennsylvania State in the USA. Further studies have supported Bernstein’s earlier work, and it is astonishing how much variability there is in each movement trajectory of a complex action that is goal orientated. Mark has suggested that this is not a redundancy problem, but rather one of abundancy, with the multiple choices available being of benefit to the body of any individual performing repetitive tasks, potentially from a fatigue resistance and injury prevention perspective, which may occur if the same muscle fibres in the same muscle are used in the same way in a repetitive manner. Interestingly, when a person suffers a stroke or a traumatic limb injury, the quantity of movement variability appears to paradoxically reduce rather than increase after the stroke or injury, and this reduced variability of motor function is associated with a decrement in task performance accuracy and completion. Therefore, the high variability of movement patterns in healthy folk appears to paradoxically make task performance more accurate and not just more efficient.

How control processes choose a specific ‘pattern’ of muscle activity for a specific task is still not well known. A number of theories have been proposed (generally as a rule in science, the more theories there are about something, the more the likelihood there is that there is no clarity about it) with some quaint names, such as the equilibrium point hypothesis, which suggests that choice at the motor neuron level is controlled as part of the force-length relationship of the muscle; the uncontrolled manifold hypothesis, which suggests that the central nervous system focuses on the variables needed to control a task and ignores the rest (the uncontrolled manifold being those variables that do not affect task required activity); and the force control hypothesis, which suggests that the central nervous systems compares the required movement for the task against internal models, and then uses calculations and feedforward and feedback control mechanisms to direct activity against that set by the internal model; amongst others. All these are interesting and intellectually rigorous theories, but don’t tell us very much about exactly how the brain chooses a particular group of muscles to perform a task, and then subsequently a different group of muscles, which use a different flight trajectory, to perform the task again when it is repeated. It has been suggested that there are ‘synergistic sets’ of muscles which are chosen in their entirety for a single movement, and that the primitive reflexes or central pattern generators in the spinal cord may be involved. But the bottom line is that we just do not currently know exactly what control mechanism chooses a specific set of muscles to perform one movement of a repetitive task, why different muscles are chosen each time the same task is performed sequentially, or how this variable use of muscles for the same task is managed and controlled.

We have previously suggested that a number of other activities in the body beyond that of muscle control have similar redundancy (or abundancy) in how they are regulated, or at least in respect of which mechanisms are used to control them. For example, blood glucose concentrations can be controlled not only by changes in insulin concentrations, but also by that of glucagon, and can also be altered by changes in catecholamine (adrenaline or noradrenaline) or cortisol levels, and indeed by behavioural factors such as resisting the urge to eat. Each time blood glucose concentrations are measured, the concentrations of all these other regulatory hormones and chemicals will be different ratio-wise to each other, yet their particular synergistic levels at any one point in time maintains the level of blood glucose concentrations at homeostatically safe setpoint levels. The blood glucose level is maintained whatever the variability in the regulatory factor concentration ratios, and even though this variability in choice of control mechanisms similarly creates a potential for high computational load when managing blood glucose concentrations from a control perspective. Similarly, perception of mood state or emotions are thought to have redundancy in what factors ‘creates’ them. For example we can fairly accurately rate when we feel slightly, moderately or very fatigued, but underpinning the ‘feeling’ of fatigue at the physiological level can be changes in blood glucose, heart rate, ventilation rate, and a host of other metabolites and substrates in the body, each of which can be altered in a variable ratio way to make up the sensation of fatigue we rate as slightly, moderately or very high levels of fatigue. Furthermore, fatigue is a complex sensation made up of individual sensations such as breathlessness, pounding chest, sweating, pain, and occasionally confusion, dizziness, headache and pins and needles, amongst others, a combination of which can also be differently valenced to provide a similar general fatigue rating by whoever is perceiving the sensation of fatigue. To make it even more complex, the sensation of fatigue is related to inner voices which either rate the sensation of fatigue (the ‘I’ voice) or make a judgement on it related to social circumstances or family and environmental background (the ‘Me’ voice), and it is through the final combination of these that an individual finally rates their level of fatigue, which adds another level of redundancy, or abundancy, to the factors underpinning how the ‘gestalt’ sensation of fatigue is both created and perceived. There are therefore three potential ‘levels’ of redundancy / abundancy in the signals and factors which either individually or collectively make up the ‘gestalt’ sensation of fatigue, and a corresponding increased level of computational requirements potentially associated with its final genesis, and how this perceptual redundancy / abundancy is managed by the control mechanisms which generate them is still not well known.

In summary, therefore, the presence of variability during activities of daily living across a number of different body systems is not only ‘noise’ / artefacts of testing conditions which are challenges for us researchers to have to deal with, it also appears to be part of some very complex control mechanisms which must have some teleological benefit both for optimizing movement and activity, and ensuring the capacity to sustain it without fatigue or injury to the components of the mechanism which produces it. Each time I cycle on my bike and my legs move up and down to push the wheels forward, different muscles are being used in a different way during each rotation of the wheel. Each time a darts player throws a dart, different muscle synergies are used to paradoxically create the accuracy of their throw. There is real ‘noise’ that a researcher has to remove from their recorded traces after a testing session in a laboratory, such as that caused by the study participant sweating during the trial, which can affect electrophysiological signals, and there is always a degree of measurement error, and therefore some degree of ‘noise’ is present in the variability of the recorded output for any laboratory technique that measures human function. But, equally, Bernstein’s brilliant work and observations all those years ago helped us understand that variability is inherent in living systems, and after understanding this, each time I observe data, particularly that generated during electrophysiological work such as I have used for a number of experiments in my own research career, including electromyography (EMG), electroencephalography (EEG) or transcranial magnetic stimulation (TMS), which has low standard deviations in the results sections of published research articles, I do wonder at the validity of the data and whether it has been ‘paintbrushed’ by the researchers who describe it, as my old Russian neurophysiology research colleague Mikhail Lomarev used to describe it, when he or we thought data was ‘suspect’. The inherent variability in brain and motor control systems makes finding statistical significance in results generated using routine neurophysiological techniques more difficult. It also seems to create a huge increase in the requisite control-related calculations and planning for even a simple movement, though as Mark Latash suggested, the brain is likely to not be a micro-manager, but rather some effective parsing mechanism which can both generate and utilize a large number of synergistic movement patterns in a variable manner for any task, while not utilizing much decision making power using some sort of heuristic-based decision-making mechanism. Most importantly though, it fills one with a sense of awe at the ‘magic’ of our own body, and for the level of complexity involved in both its creation and operative management, when even a simple movement like striking an object with a hammer, or cutting a piece of metal, can be underpinned by such complex control mechanisms that our brains cannot currently comprehend or make sense of.

In a laboratory in the middle of Russia nearly a century ago, Nikolai Bernstein made some astonishing observations by doing exceptional research on basic motor control, while trying to increase the productivity of soviet-era industrial work. A century later we are still scratching our heads trying to understand what his findings mean from a motor control perspective. As I type these final sentences, I reflect on this, and wonder which synergistic composition of muscle activity in my fingers are responsible for creating the actions which lead to these words being generated, and realize that each time I do so, because of the concepts of variability, redundancy and abundancy, I will probably never use an identical muscle sequence when typing other ideas into words at another future point in time. But then again, I guess the words I will be writing in the future will also be different, and daily life, like motor control programs, will always vary, always change, even though the nail on the wall on which the picture hangs becomes a permanent ‘item’, as will this article become permanent when I hit the ‘send’ button to publish it. What is never to be seen again though are the traces in the ‘ether’ of the hammer blow which embedded the nail in the wall, and the exact movement of the individual muscles in the labourers arms and hands, and in my fingers as I typed which created these words. Like magic their variability was created, and like magic their pattern has dispersed, never to recur again in the same way or place, unless some brilliant modern day Bernstein can solve their magic and mystery, reproduce them in their original form using some as yet to be invented laboratory device, and publish them in a monograph. Let’s hope that if they do so, their great work does not languish unseen for forty years before being discovered by the rest of the world’s scientists, as was Bernstein’s wonderful observations of all those years ago!

The Core Requirement And Skill Of Decision-Making In Life – Removal Of Uncertainty Is Usually Positive And Cathartic But Is Also An Ephemeral Thing

This week, for the first time since moving to New Zealand and starting a new job here, I cycled in to work, and in the early afternoon faced a tough decision regarding whether I had the level of fitness capacity to cycle back home at the end of the day. Three-quarters of the way through the ride home, I felt very tired and stopped by the side of the road, and considered phoning home and asking them to pick me up. This morning I opened the fridge and had to decide whether to have the routine fruit and yogurt breakfast or the leftover piece of sausage roll. We have been six months in our new life and job here, and we have come to that period of time of deciding whether we have made a good decision and to continue, or whether we have made a disastrous error and need to make a rapid change. As I write this my wife asks me if I planned to go to the shop later, and if so whether I could get some milk for the family, and I had to stop writing and decide on whether I was indeed going to do so as part of the weekend post-writing chores, or not. All of these activities and issues required me to make decisions, and while some of them appeared to be of little consequence, some of them were potentially life and career changing, and, even if it seems a bit dramatic, potentially life-ending (whether to continue cycling when exhausted as a fifty-something). Decisions like these have to be made by everyone on a minute by minute basis as part of their routine daily life. The importance of decision-making in our daily lives, and how we make decisions, is still controversial and not well understood, which is surprising, given how much our optimal living condition and indeed survival depends on making correct decisions, and how often we have to make decisions, some of which are simple, some of which appear simple but are complex, and some of which are overtly complex.

Decision-making is defined as the cognitive process (which is the act or process of knowing or perceiving) resulting in the selection of a particular belief or course of action from several alternative possibilities, or as a problem-solving activity terminated by the genesis or arrival of a solution deemed to be satisfactory. At the heart of any decision-making is the requirement to choose between an array of different options, all of which usually have both positive and negative potential attributes and consequences, where one uses prior experience or a system of logical ‘steps’ to make the decision based on forecasting and scenario-setting for each possible alternative choice and consequence of choosing them. One of the best theoretical research articles on decision-making I have read / been involved with is one written by Dr Andy Renfree, an old colleague from the University of Worcester, and one of the Sport Science academic world’s most creative thinkers. As a systems level, he suggested that decisions are made based on either rational or heuristic principles, the former working best in ‘small world’ environments (in which the individual making the decision has absolute knowledge of all decision-related alternatives, consequences and probabilities), and the latter best in ‘large world’ environments (in which some relevant information is unknown or estimated). As described by Andy, rational decision-making is based on the principle that decisions can only be made if certain criteria are met, namely that the individuals making the decision must be faced with a set of behavioral alternatives and, importantly, information must be available for all possible alternatives of decisions that can be made, as well as of the statistical probability of all of the outcomes of the choices that can be made. This is obviously a large amount of requisite information, and a substantial period of time would be required to make a decision based on such ‘rational’ requirements. While using this method would likely be the most beneficial from a correct outcome perspective, it would also potentially place a high demand on the cognitive processes of the individual making the decision. Bayesian decision-making is a branch of rational decision-making theory, and suggests that decision-making is the result of unconscious probabilistic inferences. In Bayesian theory, a statistical approach to decision-making is made based on prior experience, with decision making valenced (and therefore speeded up) by applying a ‘bias’ towards information that is used to make the decision which is believed to be more ‘reliable’ than other information, and ‘probability’ of outcomes being better or worse based on prior experience. Therefore, in the Bayesian model, prior experience ‘speeds up’ decision making, though all information is still processed in this model.

In contrast, heuristic decision-making is a strategic method of making decisions, which ignores information that is available but is perceived to be less relevant to the specific decision being made, and which suggests that decisions are made based on key information and variables that are assessed and acted upon rapidly, in a manner that, as Andy suggests, incorporates ‘rule of thumb’ or ‘gut feel’ thinking, which places less demands on the cognitive thinking processes of the individual. As described above, rational decision-making may be more relevant in ‘small world’ environments, in which there are usually not a lot of variables or complexity which are required to be assessed prior to making a decision, and heuristic thinking in ‘large world’ environments, which are complex environments where all information, whether relevant or not, cannot be known, due to the presence not only of ‘known unknowns’ but also ‘unknown unknowns’, and where an individual would be potentially immobilized into a state of ‘cognitive paralysis’ if attempting to assess every option available. The problem or course is that even decisions that appear simple often have multiple layers of complexity that are not overt and of which the individual thinking about them is not aware, and it can be suggested that the concept of both rational and ‘small world’ environments are potentially abstract principles rather than reality, that all life occurs as part of ‘large world’ environments, and that heuristic processes are what are used by individuals as the main decision-making principles during all activities of daily living.

Of course, most folk would perceive that these rational and heuristic models are very computational and mathematical based, and that perhaps ‘feelings’ and ‘desires’ are also a component of decision-making, or at least these are how decision-making is perceived to ‘feel’ to them. As part of the Somatic Marker hypothesis, Antonio Damasio suggested that ‘body-loop’ associated emotional processes ‘guide’ (and have the potential to bias) decision-making behavior. In his theory, somatic markers are a specific ‘group of feelings’ in the body and are associated with specific emotions one perceives when confronted with, and are related to, the facts or choices one is faced with and need to make a decision about. There is suggested to be a different somatic marker for anxiety, enjoyment, or disgust, among other emotions, based on an aggregation of body-related symptoms for each, such as heart rate changes and the associated feeling of a pounding chest, the sensation of breathing changes, changes in body temperature, increased sweat rate, or the symptom of nausea, some or all of which together are part of a certain somatic marker group which creates the ‘feeling’ of a particular emotion. Each of these physiologically based body-loop ‘states’ are capable of being components of different somatic marker ‘groups’, which create the distinct ‘feelings’ which are associated with different emotions, and which would valence decisions differently depending on which somatic marker state / emotion is created by thinking of a specific option or choice. This hypothesis is based on earlier work by William James and colleagues more than a hundred years ago, which became the James-Lange theory of emotion, which suggests there is a ‘body-loop’ required for the ‘feeling’ of emotions in response to some external challenge, which is in turn required for decision-making processes related to the external challenge. The example used to explain this theory was that when one sees a snake, it creates a ‘body loop’ of raised heart rate, increased sweating, increased breath rate and the symptom of nausea, all of which in turn create the ‘feeling’ of fear once these ‘body-loop’ symptoms are perceived by the brain, and it was hypothesized that it is these body-generated feelings, rather than the sight of the snake itself, which induces both the feeling of fear and the decision to either rapidly run away or freeze and hope the snake moves away. While this model is contentious as it would make reactions occur slower than if a direct cognitive decision-making loop occurred, it does explain the concept of a ‘gut feel’ when decision-making. Related to this ‘body-loop’ theory, are other behavioral theories about decision-making, and it has been suggested that decisions are based on what the needs, preferences and values of an individual are, such as hunger, lust, thirst, fear, or moral viewpoint, but of course all of these could equally be described as components of either a rational or heuristic model, and psychological / emotional and cognitive / mathematical models of decision-making are surely not mutually exclusive conditions or theories.

These theories described above attempt to explain how and why we make decisions, but not what causes decisions to be right or wrong. Indeed, perhaps the most relevant issue to most folk is why they so often get decisions wrong. A simple reason may be that of ‘decision fatigue’, whereby the quality of decision-making deteriorates after a prolonged period of decision-making. In other words, one may simply ‘run out’ of the mental energy which is required to make sound decisions, perhaps due to ongoing changes in ‘somatic markers’ / body symptoms each time a decision is required to be made, which creates an energy cost that eventually ‘uses up’ mental energy (whatever mental energy is) over the period of time sequential decisions are required to be made. Astonishingly, judges working in court have been shown to make less favorable decisions as a court session progresses, and the number of favorable decisions improves after the judges have had a break. Apart from these data suggesting that one should ask for a court appearance early on in the morning or after a break, it also suggests that either physical or mental energy in these judges is finite, and ‘runs out’ with prolonged effort and the use of energy focusing on decision-making related to each case over the time period of a court session. There are other more subtle potential causes of poor-decision making. For example, confirmation bias occurs when folk selectively search for evidence that supports a certain decision that they ‘want’ to make, based on an inherent cognitive bias set in their mind by past events or upbringing, even if their ‘gut’ is telling them that it is the wrong decision. Cognitive inertia occurs when folk are unwilling to change their existing environment or thought patterns even when new evidence or circumstances suggest they should. People tend to remember more recent information and use it preferentially, or forget older information, even if the older information is potentially more valid. Repetition bias is caused by folk making decisions based on what they have been told, if it has been told to them by the greatest number of different people, and ‘groupthink’ is when peer pressure to conform to an opinion or group action causes the individual to make decisions they would not do if they were alone and not in the group. An ‘illusion of control’ in decision-making occurs where people have a tendency to under-estimate uncertainty because of a belief that they have more control over events that they actually have. While folk with anxiety tend to make either very conservative or paradoxically very rash decisions, sociopaths, who are thought to have little or no emotional ‘body-loop’, are very poor at making moral based decisions or judgments. Therefore, there are a whole lot of different factors which can impact negatively on decision-making, either due to one’s upbringing or prior history impacting on the historical memory which is used to valence decisions, or due to one’s current emotional or psychological state having a negative impact on decision-making capacity, and even simple fatigue can be the root cause of poor decision-making.

At the heart of decision-making (excusing the pun, from the perspective of the somatic marker hypothesis), is a desire of most folk to remove uncertainty from their lives, or change their life or situation to a better state or place as a result of their decision, or to remove a stressor from their life that will continue unless they make a decision on how to resolve it, remove it, or remove themselves from whatever causes the stressor. However, during my days as a researcher at the University of Cape Town, we suggested that conditions of uncertainty and certainty associated with information processing and decision-making are cyclical (we called it the ‘quantal packet’ information processing theory, for those interested). A chosen decision will change a position or state of uncertainty to one of certainty as one enacts changes based on the decision (or if one chooses to ‘wait and see’ and not alter anything) from the context that one is certain a change will occur based on what one has decided to do, even if one cannot be sure if this difference will be positive or negative while the changes are being enacted. However, with the passing of time, the effects of the decision made will attenuate, and uncertainty will eventually re-occur which require a further decision to be made, often with similar choices to which occurred when the initial decision was made. Underpinning this attenuation of the period of ‘certainty’ is the concept that although one will have factored in ‘known unknowns’ into any decision one makes using either rational or heuristic principles, ‘unknown unknowns’ will surely always occur that will cause even the best strategic decisions to require tactical adjustments, and those that are proven to be an error will need to be reviewed and changed. One can also ‘over-think’ decision-making as much as one can ‘under-think’ it, as well as being kept ‘hostage’ to cognitive biases from one’s past which continuously ‘trip one up’ when making decisions, despite one’s best intentions. Having said all of this, it often astonishes me not that folk get decisions wrong, but rather that they get so many decisions right. For example, when driving along a highway, one is reliant on the correct decisions of every driver that passes for one’s survival, from how much they choose to turn their steering wheel, to how much they use their brake for a corner, to an awareness in each of them that they are not too tired to be driving in the first place. It’s amazing when one thinks of how many decisions we make, either consciously or unconsciously, which so often turn out right, but equally it is the responsibility of each of us to work on the errors created by our past, or by our emotional state, or by ‘groupthink’, which we need to be vigilant about and remove as best possible from the psyche.

Making a decision is usually cathartic due to the removal of uncertainty and the associated anxiety which uncertainty often causes, even if the certainty and feeling of goodwill generated by making a decision is usually ephemeral and lasts only for a short period of time before other matters occupy one’s attention which require further decision-making. Pondering on my decision-making of the last week retrospectively, I think I made the right decision when choosing to cycle home after work, and to do so all the way home, even if I was exhausted when I got there, given that I did not collapse or have a heart attack when doing so, and there will surely be long term health benefits from two long cycles (though of course long is relative at my age!) in one day. I did choose the healthy food alternative for breakfast this morning, even though often I don’t, particularly during meals when I am tired after a long day’s work. I will get the milk my wife asked me to get this afternoon, in order to both get some fresh air after a creative morning of thinking and writing, and to maintain the harmony in our house and life, even though it is raining hard and I would prefer to be writing more or reading a good book this afternoon. The ‘jury is still out’ about whether this move to New Zealand and a new work role has been a good career and country move, and my current decision on this is to let more time pass before making an action-generating reasoned decision on it, though of course we have already moved several times to new places round the world in the last two decades, and the family is looking forward to some lifestyle stability in the next few years, and these factors need to be part of any reflection on a current-environment rating decision. Each of these decisions seemed ostensibly relatively simple to make when I made them, yet each surely had an associated entire host of different reasons, experiences, memories and requirements which were worked through in and by my mind before making them, as will be so for all folk making decisions on all aspects of their life during a routine day. What will I have for lunch now I am finished writing this and am now tired and in need of a break and sustenance? Perhaps I will leave off that decision and relax for a period of time before making lunch-related choices, so as not to make a fatigue-induced bad decision, and reach for that sausage roll, which still is in the fridge. And I need to get going and enact that decision I made to get the milk, and head off to the shops in order to do so as soon as possible, before lethargy set in and I change my mind, otherwise I will surely be in the ‘dog box’ at home later this afternoon, and my sense of cathartic peace resulting from having made these decisions will be even more ephemeral than usual!

Strategy, Tactics And Objectives – In The Words Of The Generals, You Can’t Bake A Cake Without Breaking A Few Eggs

I have always enjoyed reading history, and particularly military history, both as a hobby and as a way of learning from the past in order to better understand the currents and tides of political and social life that ‘batter one’ during one’s three score and ten years on earth, no matter how much one tries to avoid them. Compared to folk who lived in the first half of the twentieth century, I perceive that we have lived our contemporary lives in an environment that is relatively peaceful from the context that there has been no world-war or major conflict for the last 70 or 80 years, though the world-wide political fluxes recently, particularly in the USA and Europe / UK, are worrying, as is the rising nationalism, divisive ‘single choice’ politics, intolerance of minorities, and increasing number of refugees searching for better lives, all eerily reminiscent of what occurred in the decade before the American Civil War and both World Wars. I recently read (or actually re-read – a particularly odd trait of mine is that I often read books a dozen or more times if I find something in them important or compelling from a learning perspective) a book on the Western Allies European military strategy in the second World War, and of the disagreements that occurred between the United States General (and later President) Dwight Eisenhower and British General Bernard Montgomery over strategy and tactics used during the campaign, and how this conflict damaged relations between the military leaders of the two countries almost irreparably. I also re-read two autobiographies of soldiers involved in the war, the first by Major Dick Winters, who was in charge of a Company (Easy Company) of soldiers in the 506th Parachute Infantry Regiment of the 101st USA Airborne Division, and the second an (apparently) autobiographical book written by Guy Sajer (if that was indeed his name), a soldier in the German Werhmacht, about his personal experiences first as a lorry driver, then as a soldier on the Eastern front in the GrossDeutschland Division, and was struck by how different both the two books were in content compared to the one on higher European military strategy, and also how different the experiences were between Generals and foot soldiers, even though they were all involved in the same conflict. All this got me thinking of objectives, strategy and tactics, and how they are set, and how they impact on the folk that have to carry them out.

Both strategy and tactics are developed in order to achieve a particular objective (also known as a goal). An objective is defined as a desired result that a person or system envisions, plans, and commits to achieve. The leaders of most organizations, whether they are military, political, academic or social set out a number of objectives they would like to achieve, for the greater good of the organization they lead (though it is never acknowledged, of course, that they – the leaders – will get credit or glory for achieving the objective, and that this is often an ‘underlying’ objective in itself). In order to achieve an objective, a leader, or group of leaders, set a particular strategy in order to do so. There are a number of different definitions of strategy, including it being a ‘high level’ plan to achieve an objective under conditions of uncertainty, or making decisions about how to best use resources available in the presence of often conflicting options, requirements and challenges in order to achieve a particular objective. The concept underpinning strategic planning is to set a plan / course of action that is believed that will be best suited to achieve the objective, and stick to that plan until the objective is achieved. If conditions change in a way that makes sticking to the strategy difficult, then tactics are used to compensate and adjust to the conditions while ‘maintaining’ the overall strategic plan. Tactics as a concept are often confused with strategy – but are in effect the means and methods of how a strategy is implemented, adhered to, and maintained, and can be altered in order to maintain the chosen strategy.

What is strategy and what are tactics becomes challenging when there are different ‘levels’ of command in an organization, with lower levels having more specific objectives which are individually required in order to achieve the over-arching objective, but which require the creation of specific ‘lower-level’ strategy, in order to reach the specific objective being set, even if the objective is a component of a higher level strategic plan. From the viewpoint of the planners that create the high-level / general objective strategy, the lower level plans / specific objectives would be tactics. From the viewpoint of the planners that set the lower-level strategy needed to complete a specific component of the general strategy, their ‘lower level’ plans would be (to them) strategy rather than tactics, with tactics being set at even lower levels in their specific area of command / management, which in turn could set up a further ‘debate’ about what is strategy and what is tactics at these even ‘lower’ level of command. Even the poor foot soldier, who is a ‘doer’ rather than a ‘planner’ of any strategic plan or tactical action enacted as part of any higher level of command, would have their own objectives beyond those of the ‘greater plan’, most likely that of staying alive, and would have his or her own strategic plan to both fulfil the orders given to them, but stay alive, and tactics of how to do so. So in any organization, there are multiple levels of planning and objective setting, and what is strategy and what is tactics often becomes confused (and often commanders at lower level of command find orders given to them inexplicable, as they don’t have awareness of how their particular orders fit into the ‘greater strategic plan’), and this requires constant management by those at each level of command.

It is perhaps not being clear about what the specific objectives behind the creation of a particular strategy are which causes most command conflict, and is what happened in the later stages of the second World War as one of the main causes of the deterioration of the relationship between Dwight Eisenhower and Bernard Montgomery. The objective of the Allies in Western Europe was relatively simple – enter Europe and defeat Germany (though of course the war was mostly won and lost on the Eastern front due to Russian sacrifice and German strategic confusion) – but it was the strategy of how this was to happen which led to the inter-ally conflict, of which so much has been written. Eisenhower was the supreme Allied Commander, and responsible for all the Allied troops in Western Europe, and for setting the highest level of strategic planning. He decided on a ‘broad front’ strategy, where different Army Groups advanced eastwards across Europe after the breakout from Normandy, in a line from the northern coast of Europe to the southern coastline of Mediterranean Europe. Montgomery was originally the commander of all Allied ground troops in Europe, then after the Normandy breakout became commander of the 21st Army group, which was predominantly made up of British and Commonwealth troops (but also containing a large contingent of American troops), and he favoured a single, ‘sharp’ method of attacking one specific region of the front (of course choosing an area for attack in his own region of command). Montgomery’s doctrine was that which most strategic manuals would favour, and Eisenhower was sharply criticized by military leaders both during and after the war for going against the accepted strategic ‘thinking’ of that time. But Eisenhower of course had not just military objectives to think about, and had also political requirements too, and had to maintain harmony between not just American and British troops and nations, but also a number of Commonwealth countries troops and national requirements. If he had chosen one specific ‘single thrust’ strategy, as Montgomery demanded, he would have had to choose either a British dominated or American dominated attack, led by either a specific British or American commander, and neither country would have ‘tolerated’ such ‘favouritism’ on his part, and this issue was surely a large factor when he decided on a ‘broad front’ strategy. There was clearly military strategic thinking on his part too – ‘single thrust’ strategies can be rapidly ‘beaten back’ / ‘pinched off’ if performed against a still-strong military opposition, as was the case when Montgomery chose to attack on a very narrow line to Arnhem, and this was more than a ‘bridge too far’ – the German troops simply shut off the ‘corridor’ of advance behind the lead troops and the Allies were forced to withdraw in what was a tactical defeat for them. Montgomery criticized Eisenhower’s ‘broad front’ as leading to, or allowing, the ‘Battle of the Bulge’ to occur, when the German armies in late 1944 counter-attacked through the Belgium Ardennes region towards Antwerp, and caused a ‘reverse bulge’ in the Allied ‘broad front’ line, but in effect the rapidity with which the Allies closed down and defeated this last German ‘counter-thrust’ paradoxically provided evidence against the benefits of Montgomery’s ‘single thrust’ strategy, even though he used the German Ardennes offensive to condemn Eisenhower’s ‘broad front’ strategy. Perhaps Eisenhower should have been more clear about the political nature of his objectives and the political requirements of his planning, but then he would have been criticized for allowing political factors to ‘cloud’ what should have been purely military decisions (at least by his critics), so like many leaders setting ‘high level’ strategy, he was ‘doomed’ to be criticized whatever his strategic planning was, even if the ‘proof was in the pudding’ – his chosen strategy did win the war, and did so in less than a year after it was initiated, after the Allies had been at war for more than five years before the invasion of Western Europe was planned and initiated.

Whatever the ‘high level’ strategic decision made by the Generals, the situation ‘on the ground’ for Company leaders and foot soldiers who had to enact these strategies was very different, as was well described in the books by Dick Winters (the book became a highly praised TV series – Band of Brothers) and Guy Sajer. Most of the individual company level actions in which Easy company participated in bordered on the shambolic – from the first parachute drop into enemy held France where most of the troops were scattered so widely that they fought mainly skirmishes in small units, to operations supporting Montgomery’s ‘thrust’ to Arnhem which were a tactical failure and resulted in them withdrawing in defeat, to the battle of Bastogne which was a key component of the battle of the ‘Bulge’, where they just avoided defeat and sustained heavy casualties, and only just managed to ‘hold on’ until reinforcements arrived. A large number of their operations described were therefore not tactically successful, yet played their part in a grand strategy which lead to ultimate success. The impact of the ‘grand strategy’ on individual soldiers was horrifyingly (but beautifully from a writing perspective) described and a must read for any prospective military history ‘buffs’ in Guy Sajer’s autobiography – most of his time was spend marching in bitter cold or thick mud from one area of the Eastern front to another as his Division was required to stem yet another Russian breakthrough, or trying to find food with no formal rations being brought up to them as the Werhmacht operational management collapsed in the last phases of the war, or watching his friends being killed one by one in horrific ways as the Russian army grew more successful and more aggressive in their desire for both revenge and military success. There was no obvious pattern or strategy to what they were doing at the foot soldier level, there were no military objectives that could be made sense of at the individual level he described, rather there was only the ‘brute will to survive’, and to kill or be killed, and only near the end, did he (and his company level leaders) realize that they were actually losing the war, and their defeat would mean the annihilation of Germany and everything they were fighting for ‘back home’. Yet is was surely the individual actions of soldiers in their thousands and millions that endured and died for either side, that in a gestalt way lead to the strategic success (or failure) planned for by their leaders and generals, even if at their individual level they could make little sense of the benefit of their sacrifice in the context of the broader tactical and strategic requirements, in the times when they could reflect on this, though surely most of their own thoughts were on surviving anther terrible day, or another terrible battle, rather than on its ‘meaning’ or relevance.

One of the quotes that I have read in military history texts that has caused me to reflect most about war and strategy as an ‘amateur’ military history enthusiast is attributed to British World War Two Air Marshal Peter Portal, who when discussing some what he believed to be defective strategic planning with his colleague and army equal Field Marshal Alan Brooke, apparently suggested that ‘one cannot make a cake without breaking some eggs’. What he was saying, if I understood it, and the comment indeed can be attributed to him, was that in order for a military strategy to be successful, some (actually most of the time probably many) individual solders have to be sacrificed and die for the ‘greater good’ which would be a successfully achieved objective. From a strategic point of view he was surely correct, and often Generals who don’t take risks and worry too much about their soldiers safety can paradoxically often cause more harm than good by developing an overly cautious strategy which has an increased risk of failure and therefore an increased risk of more soldiers dying. But from a human point of view the comment is surely chilling, as each soldier’s individual death, often in brutal conditions, is horrific both to those that it happens to and those relatives, friends and colleagues that survive them. Often, or perhaps most of the time, individual soldiers die without any real understanding of the strategic purpose behind their death, and with a wish just to be with their loved ones again, and to be far from the environment and actions which cause their death. The folk at senior leadership levels setting grand strategy require a high degree of moral courage to ‘see it through’ to the end, knowing that their strategy will surely lead to a number of individual deaths. The folk who enact the grand strategy ‘in the trenches’ need a high degree of physical courage to perform the required actions to do so in conditions of grave danger, that as a small part of the ‘big picture’ may help lead to strategic success and attainment of the set objectives, usually winning in a war sense. But every side has its winners and its losers, and there is usually little difference between these for the foot soldier or Company leader, who dies in either a winning or losing cause, with little knowledge of how their death has contributed in any way to either winning or losing a battle, or campaign, or war.

Without objectives, strategy and tactics, there would never be any successful outcome to any war, and a lot of soldiers would die. With objectives, tactics and strategy, there is a greater chance of a successful outcome to any war, but a lot of soldier will still surely die. The victory cake tastes wonderful always, but always, sadly, to make such a ‘winners’ cake, many eggs do indeed need to be broken. It will long be controversial which is more important in the creation of the cake, the recipe or the eggs that make it up. Similarly, it will long be controversial whether it is relevant whether a ‘broad front’ or ‘single thrust’ strategy was the correct strategic or tactical approach to winning the war in Western Europe. But, the foot solder would surely not care whether his or her death was in the cause of tactical or strategic requirements, or happened during a ‘broad front’ or ‘single thrust’ strategy, when he or she is long dead and long forgotten, and historians are debating which General deserves credit for planning the strategy, or lack of it, that caused their death. That’s something I will ponder on as I reach for my next book on war strategy that fill the book shelf next to my writing desk, and hope that my children will never be in the position of having to be either the creators, or enactors, of military strategy, tactics and objectives.
