All of the sports have a safety net, but boxing is the only sport that has none. So when the fighter is through, he is through. While he was fighting his management was very excited for him, but now that he is done, that management team is moving on.

Like I say, boxing was on the floor, but it got back up.

A lot of the athletes moved away from boxing, into UFC - which I think is really crazy, where they elbow to the head and knee to the jaw. I think that's really a barbaric sport - but boxing is coming back.

The way to beat the Klitschkos is to get inside, under the jab, and bang to the body. Do that for two or three or four rounds and then the hands will come down and then you turn them over. It's like chopping a tree down. These guys try to headhunt when they fight them and that won't work. But you back them up, the younger brother especially, and he loses heart.

If you look at my career, towards the end you will see I was fighting like once a year. I was not part of the Don King top heavyweights, so I was kind of kept out. His guys were getting three to four fights a year and I could only get one.

You have a small period of time when you can perfect your career and become good at it. A lot of guys get distracted, which only hurts them. You must stay focused and work very hard at boxing.

By the time you're 30 years old, you can be on a nowhere street, if you're not careful.
