I'm a performer. We don't retire.

I've been a boxing fan ever since I was a kid.

Joe Louis was one of my first heroes.

I can tell jokes. I can talk to the audience. I can relax. I can change my songs whenever I want. I can change the tempos. I can change the mood, because I'm in charge.

I'm a performer. We don't retire.

But I don't work out. I pay people to do that for me.

Ali and I have become friends over the years. I was on a plane with him one time when he was the champion.
