A lot of guys are out there with their iPods. I'm not one of them. I just never really got into it.

I played a kid's game, I got to do it at the beach, and I was able to support my family. I consider myself incredibly lucky.

We play at the world's most beautiful beaches but in the world's most challenging conditions. It is not like you play one match and you go back to air conditioning. We do it all day long.

The exercises helped get the flexibility back in my ankle and also increased my overall flexibility. As I was getting into my 30s, I wanted to do everything I could to improve my longevity.

My dad was a really intense competitor and that rubbed off on me. He was loud and vocal on the court, so I let him do all the talking. But I developed a kind of quiet intensity that I knew I had to have to improve and compete with grown men. It took every ounce of focus.

Physically I'm not as strong as I was, but I try to make up for it mentally. It's a big challenge, and I relish it, competing with guys half my age.

I just think about what I am doing on my side of the net, which requires focus. Even after all the years I've been playing, I still get butterflies before each match.
