Body Quote by Edwin Catmull
“I exercise in the gym about three times a week. I vary the workout every time, but I'll always do some type of circuit work with weights. It gets my heart rate up without putting too much stress on my knees, which for some reason seem to be older than the rest of my body.”

I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
