But if I keep my core and back strong, the scoliosis doesn't really bother me.

There are things that bother me. I try not to let them, but they do.

Since they came in with the selfie, it's the worst thing. You hardly ever get asked for autographs any more. It's always selfies.

If you feel strongly about something and you want to voice your opinion, I feel it's your right, so, that's how I look at it because that's how life is.

I remember once, actually the first race I ran, I fell.

Racing comes easily to me, especially the 100 metres. That is why, no matter how fast I run the run the 100 metres, the 200 will always mean more to me, because of the effort I've put in.

I am now a legend. I am also the greatest athlete to live.
