I was young. I was newly married. And I had worked like a dog. I just wanted to live and travel.
After the loss of Columbia a couple of years ago, I think we were reminded of the risk. All of us, though, have always known that the Space Shuttle is a very risky vehicle, much more risky than even flying airplanes in combat.
When I'm out on the stage, it gives me this rush and anything that's on my mind and everything I'm going through is forgotten about.
