I should say that mental strength is No. 1, experience [is] No. 2, physical strength is No. 3, and genetic ability that you're getting from Mother Nature probably comes after.

These nuclear plants are more dangerous than people realize.

You have to learn the opponent psychologically inside out and mental strength is one of the important makers. You're either gonna break it or make it.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

My height is an advantage, if I want to use it.

I run, but boxing conditioning is different, so you have to get used to running in the ring. Boxing movements are very different. Swimming is one of the best because every single muscle is working. I swim a lot. I train very hard at things that mimic boxing. I have to do mostly sport-specific training, such as lots of sparring.

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.
