As if this was not enough, we have fallen into the new habit of thinking our way into illness. If we take up the wrong kind of personality, we run the risk of contracting a new disease called stress, followed quickly by coronary occlusion. Or if we just sit tight and try to let the world slip by, here comes cancer, from something we ate, breathed or touched. No wonder we are a nervous lot. The word is out that if we were not surrounded and propped up by platoons of health professionals, we would drop in our tracks.
The truth is something different, in my view. There has never been a time in history when human beings in general have been statistically as healthy as the people now living in the industrial societies of the Western world. Our average life expectancy has stretched from 45 years a century ago to today's figure of around 75. More of us than ever before are living into our 80s and 90s. Dying from disease in child hood and adolescence is no longer the common occurrence that it was 100 years ago, when tuberculosis and other lethal microbial infections were the chief causes of premature death. Today, dying young is a rare and catastrophic occurrence, and when it does happen, it is usually caused by trauma.
Medicine must get some of the credit for the remarkable improvement in human health, but not all. The profession of plumbing also had much to do with the change. When sanitary engineering assured the populace of uncontaminated water, the great epidemics of typhoid fever and cholera came to an end. Even before such advances, as early as the 17th century, improvements in agriculture and nutrition had in creased people's resistance to infection.
In short we have come a long way—the longest part of that way with common sense, cleanliness and a better standard of living, but a substantial recent distance as well with medicine. We still have an agenda of lethal and incapacitating illnesses to cause us anxiety, but these shouldn't worry us to death. The diseases that used to kill off most of us early in life have been brought under control.
