I think that boxing is actually not as dangerous as the politics. In boxing, you're gonna get a bloody nose or a black eye. In politics you can obviously get either dioxin in the food or bullet in the head.

Politics is comparable to boxing. The only thing is that in politics there are basically no rules. In boxing, you can get a black eye, but in politics you can get poison in your food or a bullet in the head. It's definitely rougher and tougher than other sports.

I have a Ph.D. in philosophy and sports science. At 14, I went through this really tough Soviet training system. A lot of my roommates got psychologically broken or physically injured. Either you came through, or you were out. I made my Ph.D. work in the field of young athletes aged 14-19 because at this age any human is changing.

I would say that Roger Federer is pretty amazing. And Manny Pacquiao - he's such a tiny, little lightweight guy, but the way he fights makes people so excited.

I prepare for my fights to well that I don't wanna give a chance to my opponent to crash my 'glass chin' as they say, so I'm knocking them in the way that I like.

I'm playing right now a role, and the role is called the 'Heavyweight Champion of the World.' And it takes all of the time. And I love this role, and it takes a lot of attention for me for the sport, and I just don't want to lose the title, so that's why I have to stay focused and not become an actor.

I think a fight with David Haye, even if he is not American, is going to give positive vibes about the heavyweight division for the American fans and fans worldwide.
