OBM points to an interesting piece by Malcolm "Tipping Point" Gladwell on performance enhancers/enablers in sports. The piece was published the day before 9/11 (yes, that would be 9/10) so maybe no one paid attention to it at the time. Gladwell:

We have come to prefer a world where the distractable take Ritalin, the depressed take Prozac, and the unattractive get cosmetic surgery to a world ruled, arbitrarily, by those fortunate few who were born focussed, happy, and beautiful. Cosmetic surgery is not "earned" beauty, but then natural beauty isn't earned, either. One of the principal contributions of the late twentieth century was the moral deregulation of social competition--the insistence that advantages derived from artificial and extraordinary intervention are no less legitimate than the advantages of nature. All that athletes want, for better or worse, is the chance to play by those same rules.
