I never look backwards. I have always been an athlete. I boxed before I acted.

Boxers are very isolated - or isolated within their own camps.

The two sports are as different as Ping-Pong and rugby. In boxing, you don’t know what’s going to happen. In wrestling, it’s already prearranged. But the thing I didn’t know about wrestling is that you really get hurt. Because, you know, you’re wrestling in front of a live audience, and you end up doing things like jumps or slams, and 40 percent of the time you don’t land right.

I started having some memory-loss issues. I took a neurological exam, and they said, "Well, you should stop fighting now." And I kept begging them for one more fight, one more fight, and the doctor said to me, "How much are they going to pay you?" I was supposed to fight three more times, and one would have been for a cruiser belt. So I said, "I just need to fight three more times." He said, "Listen, you can't even get hit in the head one more time, your neuro is so bad."

A couple of guys won Academy Awards for the things that I turned down. Today, after coming to terms with everything, after being in therapy for a long time-there are areas where I will compromise.

Julian Schnabel painted a picture that he dedicated to my character in Rumble Fish. It was called The Motorcycle Boy. I remember when he brought it over to me at the Mayflower Hotel [in New York] years ago. This is when you and I knew each other.

I never knew my father, and I'd hate to repeat that kind of cycle with my own children, because I'd also want to be there for them no matter what.
