To this he replied: "Out of the tens of thousands of prosthetic legs they've made, there's never been any 400-meter athletes run under 50 seconds.

Oscar Pistorius was once an inspiration to many throughout the globe. During his glory days, the South African Olympian has often given inspirational messages to fans.
"I don't see myself as disabled. There's nothing I can't do that able-bodied athletes can do," the Paralympic gold medalist once said. That was the kind of person he was, before being arrested for his girlfriend's death.
Pistorius was born with fibular hemimelia and his lower limbs were amputated at the age of 11 months. At the age of two, he was given prosthetic legs and he gradually mastered using them. His parents never let disability come in his way.
His father wrote a letter to Pistorius before the operation, which read "a loser isn't the person that gets involved and comes last, but the one who doesn't get involved". This message became a part of his life story.
But since February 2013, Pistorius' has been in the news for the wrong reason - shooting and killing his model girlfriend Reeva Steenkamp. And after months long trial, the verdict came on 11 September 2014 - finding him guilty of culpable homicide.
Let's take a look at the 27-year-old' career.
