Human bodies are extremely complicated and over the years I learned three important things about them, none of which I had been taught by lecturers or professors at my medical school. First, I learned that no two bodies are identical and there are an infinite number of variations. Not even twins are truly identical. When I first started to study medicine I used to think how much easier it would be for us all (doctors and patients) if bodies came with an owner's manual, but the more I learned about medicine the more I realised that such a manual would have to contain so many variations, footnotes and appendices that it wouldn't fit into the British Museum let alone sit comfortably on the average bookshelf. Even if manuals were individually prepared they would still be too vast for practical use. However much we may think we know about illness and health there will always be exceptions; there will always be times when our prognoses and predictions are proved wrong. Second, I learned that the human body has enormous, hidden strengths, and far greater power than most of us ever realise. We tend to think of ourselves as being delicate and vulnerable. But, in practice, our bodies are tougher than we imagine, far more capable of coping with physical and mental stresses than most of us realise. Very few of us know just how strong and capable we can be. Only if we are pushed to our limits do we find out precisely what we can do. Third, I learned that our bodies are far better equipped for selfdefence than most of us imagine, and are surprisingly well-equipped with a wide variety of protective mechanisms and self-healing systems which are designed to keep us alive and to protect us when we find ourselves in adverse circumstances. The human body is designed for survival and contains far more automatic defence mechanisms, designed to protect its occupant when it is threatened, than any motor car. To give the simplest of examples, consider what happens when you cut yourself. First, blood will flow out of your body for a few seconds to wash away any dirt. Then special proteins will quickly form a protective net to catch blood cells and form a clot to seal the wound. The damaged cells will release special substances into the tissues to make the area red, swollen and hot. The heat kills any infection, the swelling acts as a natural splint - protecting the injured area. White cells are brought to the injury site to swallow up any bacteria. And, finally, scar tissue builds up over the wounded site. The scar tissue will be stronger than the original, damaged area of skin. Those were the three medical truths I discovered for myself. Over the years I have seen many examples of these three truths. But one patient always comes into my mind when I think about the way the human body can defy medical science, prove doctors wrong and exhibit its extraordinary in-built healing power.
