It sounds funny, but the 2008 Olympics were something that just kind of happened, and I was lucky they came at a point when I was uninjured and well prepared. As a gymnast, you can't ask for much more.

The sport would not survive today if drivers were being killed at the rate they were in the 1960s and '70s. It would have been taken off the air. It is beamed into people's living rooms on Sunday afternoons, with children watching.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
