I’m amazed at how many of my 80-year-old friends are quite functional.  That would have been something I never would have thought possible when I was 20 years old.  I’m hoping I’m still at my peak as a tennis player.  

For my 80th birthday I was given the racket that Roger Federer plays with.  It’s a good racket, and it let’s me play better.  But, in all honesty, I can’t believe that I'll be doing this 10 years from now.  I just think I’ll slow down some.  And I don’t want to.  

I think we’re all in favor of being alive when we’re alive.  And of course, it's how you define being alive.
