There's always a chance. Anything can happen.

My approach to gymnastics in Beijing was heavily based on the amount of difficulty I could do.

I was always trying to be leaner and thinner to fit the standard and the mold.

It might have been easier to retire, to say my knee couldn't handle it and let that be that. At the same time, the prospect of not being able to compete in gymnastics anymore was heartbreaking.

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.

I have a chaperone everywhere I go - my mom.

It's nearly every country's tactic to keep their greatest competitors a secret.
