Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm.

The whole key is to be honest with yourself, find the weak spots, work on it, get it done.

When you're successful for so many years, the scariest part is that you're getting too comfortable because you've had so much success.

Earlier in my career, I never thought of boxing as a chess game, but I confirm that they are, in fact, very similar. You can plan your fights and strategy just like you would in chess.

All of my fights are planned. I study my opponents from A to Z. How he walks, how he looks, how he speaks, gestures of the human body, which is a certain language that provides you lots of information if you have the ability to read it.

Mental strength is really important because you either win or lose in your mind.

The challenge for me is his size because, for the first time in my career, I'll be meeting an opponent who is taller than me and has a longer reach.
