Proves my point even more.

It doesn't prove anything of the sort.

One cannot expect a tennis player to run around the court once he hits around 35.

If Federer ends up with the most grand slams ever, the case for him will be much stronger.

But, yes, Tiger will still be playing probably into his fifties, and be the all-time everything in golf. I favor Tiger now, but Roger too is dominant at his sport.

"It doesn't prove anything of the sort."

It sure does.
Numbers don't lie.

"One cannot expect a tennis player to run around the court once he hits around 35."

Precisely my point.

"If Federer ends up with the most grand slams ever, the case for him will be much stronger."

So long as Tiger doesn't end up with more slams than anyone ever as well. Right now, I am going to go for Tiger eclipsing Jack Nicklaus's record by the end of his carrier, and ending up with more golf slams than anyone else in history.
