I will cross that bridge when it comes. I am not stupid. I am a very bright guy. I know that in the fighting game, you get people who get brain damage and do themselves long-term harm. I am into it in a big way, and I am good at it, and I am going to get very, very rich and then I will get out and we will see what comes after that.

If people want to believe in this god, or that god, that's fine by me, believe away.

Late switches are part of fighting and I've handled them all.

You need to be able to hit, kick, grapple, wrestle, but for me so much of this is about the mind, about feeling you are in complete control of the space around you, and you know what to do at any moment. That is a wonderful feeling, but it doesn't just happen, you have to work for it, train for it, think about it all the time.

I studied every move, I became fascinated by thinking what I could have done differently. And I take that approach now as a professional. I am on it, all the time, never stop thinking, learning. You don't get to be world champion unless you do that.

Ask José Mourinho, he wouldn't know a thing about me, my sport - he knows football, and to get to high levels you have to be insane, nothing else means anything.

In general, I like the healthy stuff and don't really have a problem with any of it.
