I told myself after 2008 that I was done for good. But they say you can't keep a gymnast away from her sport.

I don't think I've ever not gotten nervous. When you work so hard for one special day or routine, you want to perform it better than you ever have. We always say at our gym, If you lose the nerves, you lose the sport.

I had surgery to repair the ACL in February 2010 and was back in the gym by June, but rushed things too quickly and ended up re-tearing my MCL in September.

People only see gymnastics on TV and in the Olympics at such an extreme. So it can be intimidating.

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.

My coach, Liang Chow, had one rule while I was training for the 2008 Olympics: no skiing. I could do anything I wanted outside the gym, he said, except ski.

I have a healthy lifestyle, but there's nothing you can really do to prevent from rolling an ankle or something like that.
