For the first time ever in Olympic history, a double-amputee is set to race alongside able-bodied athletes. Nicknamed "Blade Runner," South African sprinter Oscar Pistorius's remarkable achievement is set to raise as much enthusiasm as it will concern.
As we recently reported, it's very possible that Pistorius's advanced prosthetic "Cheetahs" give him a distinct advantage. This has led some to speculate that we're not too far off from the day when perfectly functioning athletes and the general public will want to enhance themselves in this way — what's being dubbed "elective amputation." But just how real is this possibility?
