In the mid-1990s, sports medicine specialist Robert Goldman dropped a poisonous question in the locker rooms of Olympic athletes, informally wondering the following:
"If I had a drug that was so fantastic that if you took it once, you would win every competition you would enter, from Olympic decathlon to the Mr. Universe, for the next five years. But it had one minor drawback: It would kill you five years after you took it. Would you still take it?"
Fifty-two percent of those he asked said they would.
