Almost every ex -jock is on TV, hawking some "turn back the clock" dietary supplement. Ya know, "swallow this stuff and you're a randy teenager again". Or swallow this stuff, and it cures warts, heart disease, gray hair, cancer, old age, athlete's feet, and 2,000 other diseases. All those dietary supplements claim all kinds of effects, but strangely few respected medical professionals ever prescribe them. If they work that well, why don't they?? What do you think about all those 'dietary supplements" claims?
