Doping

I heard some boff on radio 4 the other week say that with or without drugs the human body can and will only go so fast.. Example of this is that the absolute record for 100m sprint will never be any quicker than 8.4 seconds..

I would think that the way the human body only uses a small percentage of theoretical muscle power. Would mean a big margin for improvement/fecking-yourself-up.

I'm no doctor though.
