As spokesman for children in foster care, Willis is encouraging system reforms and raising money for scholarships. Accepting the post in 2002 at the White House, "I just kinda stuttered through it," says Willis. "I should've been more prepared." Photo by: STEPHEN JAFFE / AFP / NEWSCOM

And all three girls want to become actresses?
The rule in our family is, they can act with their mom or with me until they're 18.

How do you feel about turning 50?
I remember when I was a kid, 50 was pretty old. I feel great. I look after myself. I can still run around and keep up with my kids. Everybody, no matter how old you are, is roughly around 24, 25 in their heart. I just did a week on a film called Alpha Dog. I had to do a stunt where I had to run at full speed and get over a wall, and I had to drop 6 1/2 feet on the other side. It was the first time I thought, I hope I don't turn my ankle or some old-man thing.

How do you stay in shape?
Mostly weight resistance training, almost an hour of cardio at least three times a week. I have a gym in my house in Los Angeles and a gym trailer that I can take on the road with me when I'm on location. At my house there's a very long steep driveway. I do wind sprints that kick my 50-year-old ass. It's part of my job. I have come to associate working out as work. Whenever I don't have to do it for films, I kind of slack off.

Is sex better at 50 or 25?
Fifty. You're in less of a hurry. You know a few more tricks. For me, you make it more about the woman. And just the simple fact that at 50 you can still do it. That's a nice little bonus by itself.

You've probably got a few more years left in you.
I'm counting heavily on science.
