I remember when I was 14, I went to race in Hungary, and I went to a concert, and they were playing Bob Marley songs, and I thought, "Wow, this guy is so special." It's Marley every time.

Where I'm from, there is no violence, pretty much.

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

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 think about racing too much you may just lose it a little bit.

I know what I can do, so I never doubt myself.

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.
