john carlin: oscar pistorius was born in 1986. it was discovered that he had this congenital deformity of his feet. and his two legs were amputated just below the knee. robyn curnow: he was very brave in terms of breaking physical boundaries. i grew up in a family where disability was never an issue, not because it was a topic that was taboo, but it was just never an issue. [light music] john carlin: and he becomes a superstar in the world of paralympics. and he's good-looking. he's got a certain greek god kind of demeanor. i think he saw himself as superhuman. and, you know, look, it was well earned. i mean, he achieved these things on the track that no one could believe he achieved. and that must be a really, really powerful thing to feel when you are born or have the disability that he had. behind that public persona, oscar did have a very real physical limitation. robyn curnow: because off his prosthetics, he is a fundamentally disabled man who can barely walk. he almost looked scared because he was vulnerable. michael sokolov
