Many conditions that are treated with pills could as effectively be addressed with proper diet, nutrition and exercise. Curiously, doctors are rarely averse to prescribing medications for most of these; it is noteworthy that obesity is treated differently. On the other hand, maybe it's time the pills were left on the shelf and patients were required to take responsibility. Big pharma wouldn't like it, but a host of side effects would be avoided, billions of dollars would be saved, and "survival of the fittest" would actually mean something in the social context.
