Oscar Pistorius of South Africa is a runner. He has no legs. They were amputated at the knee. However he has overcome this seemingly insurmountable challenge opting for prostethic limbs. His new legs are so fantastic that he is able to do anything someone on two legs can accomplish... and sometimes even better! In fact, Oscar's prostethic limbs use such advanced technology that he may be barred from competing in the Olympics on claims that his prostethics give him an unfair advantage!
