For whatever reason, maybe it's because of my story, but people associate Livestrong with exercise and physical fitness, health and lifestyle choices like that.

The day it all changed. The day I stated never to take anything for granted. The day I learned to take charge of my life. It was the day I was diagnosed with cancer.

Evan Handler is a man who’s looked into the abyss and laughed. His book, It’s Only Temporary, made me laugh along with him. He covers love, lust, showbiz, triumph, and despair – and he manages to be both funny and inspiring about all of it. It’s an important book that I think can help to spread goodness around the world.

Nineteen hundred meters up there is completely different from1,900 any place else. There's no air, there's no oxygen. There's no vegetation, there's no life. There's no life. Rocks.

There were something like 50 good, arduous climbs around Nice, solid inclines of ten miles or more. The trick was not to climb every once in awhile, but to climb repeatedly. I would do three different climbs in one day, over the course of a six- or seven-hour ride. A 12 mile climb took about an hour, so that tells you what my days were like.
