Age, what is it? It's not a figure that has ever meant anything to me.

I've thrown away lots of my old diaries - you never know who might get their hands on them. But I have kept a few notes on the good old days.

I don't wake up every day and think about which tournaments I won and which titles I hold. It's something I don't care about.

The tennis wasn't really very much on my mind, so it wasn't like I was thinking about it all the time.

If you go to a big city anywhere in the world and you need a doctor, just ask me. I can tell you who's good and who's bad. I've even considered writing a guidebook.

Tennis has always been a big challenge to me and to be able to play that kind of tennis - well, only tennis can produce these feelings for me.

It's so difficult to find time besides the tennis.
