siempre, thats the whole issue though, why do we allow those that need to wear glasses or contacts to compete? Shouldn't they only be allowed to use their own physical gifts? Why do we allow the deaf or the blind to participate in sports? (I wrestled both a blind guy and a deaf guy in high school) They get to play by special rules, you have to be touching the blind guy at all times, the deaf guy is allowed other special rules. A guy with asthma was allowed to take a break if he had an attack (in otherwords if he got tired) But allowing a guy with fake legs to run I guess that is just too far! We allow athletes to take vitamins, and other supplements, we allow them to use the most expensive technology available, but the guy with fake legs... thats too far. Its only too far, because nobody wants to admit that he is just as good as they are.
