Everyone has setbacks. I'm no different. I happen to have no legs. That's pretty much the fact.

Out of the tens of thousands of prosthetic legs they've made, there's never been any 400-meter athletes run under 50 seconds. So, if this was such a technologically advanced prosthetic leg, then how come not everyone's qualifying, or coming close to the qualification time, then?

Putting on my legs is like putting on my shoes. I understand that's how some people might think differently, but I hope that in London, their perceptions open up.

These have always been my legs. I train harder than other guys, eat better, sleep better and wake up thinking about athletics. I think that's probably why I'm a bit of an exception.

Thank you to everyone that has made me the athlete I am! God, family and friends, my competitors and supporters! You have all had a hand!

My parents didn't give me any scope to feel sorry for myself. They were just like 'go play with your brother, go climb a tree, go fall off your motorbike, do whatever you want. Don't come crying to us when you get scratched. You've got prosthetic legs - that's very nice.'
