He and many other aspiring sophisticates became smokers. Six years later - 50 years ago: Jan. 11, 1964 - when the Surgeon General published the report declaring tobacco carcinogenic, more than 40 percent of American adults smoked.




It was welcome because obesity begins early - those from age 3 to 5 are five times more likely than others to be overweight or obese as adults, when being so makes people more susceptible to cancer, heart disease and stroke. It was a surprise because no one knows why the rate dropped. A reasonable surmise, however, is that one cause is the cumulative effect of talk about sensible eating and exercising.


Mark Twain said humans are the only animals that blush - or need to. Leon Kass, University of Chicago professor emeritus now at the American Enterprise Institute, has written that humans are the only animals that do not "instinctively eat the right foods (when available) and act in such a way as to maintain their naturally given state of health and vigor.


There may be no such thing as an unmixed blessing, and there was a cost even to the conquest of polio. Americans, whose national DNA disposes them to anticipate progress to be a product of technology, interpreted the Salk vaccine as establishing what can be called the "polio paradigm." It is the mistaken idea that large improvements in public health result primarily from new medicines.


Typhoid, too, became rare before effective drugs became available. Streptomycin may have produced only 3 percent of the reduction of TB but our cultural bias is toward the improved-health-through-medical-intervention model. This produces high-tech, hospital-oriented, disease-and-therapy-centered policy.

The premise that health is the product of medicine leads government to believe it can deliver health by judiciously distributing preventive or therapeutic medicines. A significant portion of America's health care bill - caused by violence, vehicular accidents, coronary artery disease, lung cancer, AIDS, Type 2 diabetes brought on by obesity, among other problems - results from behavior widely known to be risky.

So as we wallow waist deep in the muddy debate about health care, we should remember that the relationship between increased investment in medicine and improvements in health is complex and tenuous. As Kass has said, in an era of organ transplants and the cracking of the genetic code, it seems boring to suggest that the most important path to health is a vanilla virtue - prudence.

Nevertheless, unlike oysters or ostriches or ocelots, featherless bipeds - Plato's unenthralled description of human beings - are animals that go through their days making choices. And they often make bad ones.

Such choices often require ameliorative medicine. Which illustrates this point: Although preventive medicine is real, society's level of health does not depend primarily on medicine, which too often must be resorted to when our behavior has forfeited our health.
