Double amputee Oscar Pistorius reflects on becoming the first Paralympian to compete at the World Championships.
He's "the fastest man on no legs," or -- as his sponsor's high-profile advertising campaign put it -- "the bullet in the chamber."
A man born without functioning legs ran the 400 meters in 45.07 seconds on July 19, 2011, the fastest time recorded by an amputee. The ripple effects of this historic achievement may initiate a paradigm shift in how we view our bodies.
It sounds like a Paralympic version of a barroom joke: guy with no lower arms or legs walks up to a guy born with no fibula in either leg and starts talking about running.
Eighteen months ago, South African sprinter Oscar Pistorius -- famously known as the "Blade Runner" because he was born without fibulas and runs on two crescent, carbon fiber lower legs -- made global headlines when the Court of Arbitration for Sport (CAS) overturned a ban by the International Association of Athletics Federations and allowed Pistorius to compete against able-bodied runners in international competition.
