When he was 11 months old, Oscar Pistorius had both his legs amputated below the knees because of a congenital condition. Now 21, Pistorius is a sprinter who runs on artificial legs called blades, as he did in July at the Golden Gala competition.
Pistorius can't compete in this year's Summer Olympics in Beijing because those blades have been ruled an unfair advantage. It's a shame he won't be allowed to compete. Seeing him round the turn in the 400 meters and take off, moving at world-record speed on metal prosthetics, accomplishes a feat that's rare in this world: Redefining the possible.
