Nowadays, athletes will consume just about anything to improve their abilities to run faster, jump higher and hit harder. And there's a history of some strange performance enhancing drugs that have been used to do just that — all now banned in professional sports; Adderall, deer antler spray and even female fertility pills. These make steroids look so boring.
What isn't banned, or even frowned upon, that athletes are resorting to now, is LASIK eye surgery. Not just any athletes are turning to LASIK for an advantage against their competitors. The best athletes are — superstars if you will.
