Paralympics 2012: London Games will be life-changing - Pistorius

Four-time Paralympic champion Oscar Pistorius believes the London Games will change people's perceptions about disability.

The South African says he is "extremely proud to be part of the Paralympic movement" and that reaching the semi-finals of the 400m at the Olympics was one of the highlights of his career.

Pistorius admits Briton Jonnie Peacock is a major threat to his 100m title after making a "phenomenal" improvement.
