They have an article today in the LA Times West magazine about people who keep in shape (here in So Cal) even past their "prime years." This guy made me go woof! See what you think:

A lil bio about him:
Rich Roll | 40 | Born:10/20/1966 | Occupation: Entertainment lawyer, writer and filmmaker | Hometown: CalabasasActivities: Swimming, triathlete
Starting line: I've been swimming on teams since I was about 6.
Making time: We have a lap pool at my house. Now that it's nice out, I try to go [ocean swimming] at least once a week. I generally swim at lunchtime. That's sort of sacred. Long rides and long runs on weekends. Running is a good complement to the swimming. We just had a baby, [so] I'm probably training about 12 hours a week. It's an extension of who I am and what I love.
Benefits: It helps me achieve focus in all the other areas of my life. It's as much a meditative experience as anything else. It gives me a clarity of thought. When you're swimming in the ocean, there's a purity you don't have in the pool.
"No-whining" secrets: If I'm getting stale in one endeavor I can switch to another. I also do yoga. It's an extension of a holistic lifestyle that includes diet and meditation.
Fitness mantra: I feel it's what I'm meant to do.
