Will Today's Disability Be Tomorrow's Super-ability? Prosthetic devices have reached the point where they don't just help people in need. They can make them as fit -- or fitter -- than everyone else. South African sprinter Oscar Pistorius , an amputee with question-mark-shaped carbon fiber prosthetics below his knees, may qualify for this summer's Olympic Games. Is that fair to competing runners?
