A kid who moves is a kid who learns.

I think at the age of 50, everyone should write their own autobiography.

I plan for the future, but the only day I really worry about is the day I'm living right now.

Ninety percent of people who lose weight gain it back. It's very sad.

I spent my childhood eating. The only exercise I got was trying to twist off the cap of a jar of mayonnaise.

I'm 64, but I act like I'm still 12. I go to schools. At colleges, they come out in droves, they almost scare me. I think it's just to see if I'm still alive. After I work them out - and it's not easy - I sit them down and we have a serious talk. Are they eating? Working on their body? I can say things parents won't say. No matter where I go, I talk to each one individually after I teach. They tell me things like, 'I'm starving, guys like girls thinner.' I give them concrete advice about self-image and self-worth.

Sleep is critical to me ... at least eight or nine hours a night. I start to slow down my body and my mind at least 30 minutes before I get into bed. I don't watch any disturbing or invigorating TV at night.
