This is a really cool topic-I never thought about prosthetic feet and whether or not amputees had an advantage w/ prosthetic limbs. Do runners with prosthetics run faster? Do you know of any people who had limbs amputated after they had become athletes and how they adapted, ie if, after a period of getting used to their new limbs, they ran faster, or if most were unable to regain their previous strength. I think you've done a good job showing facts about the limbs, but I'd like to hear some arguments from people who think they shouldn't be able to and peopel who think they should. I do think it's a really cool issue and I might research it a little myself.
