I remember back in the early '70s, when I had a disastrous Grand Prix, my wife, Lynn, said to me, 'Don't worry, you're going to be a late boomer.' That's what she said to me, and I've always held that thought.
I work out every morning for an hour while in front of the news channel or business channels, then I'll ride for four, five hours a day. So I'm on the move all the time, and I think that's the key. A body in motion tends to stay in motion. That's the law of physics.
