It's going to be really weird when I'm 80 years old, in a walker, and people are still calling me America's sweetheart. We need a new one.

As a kid, I was a pretty good little sprinter.

Former Olympians also get paid to make appearances. Many of them won their medals in an era when Olympic success didn't go hand-in-hand with financial success.

The endorsement game has been very good to me.

Be cocky. Walk into the Georgia Dome like you own it.
