I generally refuse to grow up - adulthood is not all that great but, you can't
cheat nature (unless you are Sly Stallone with a couple hundred shots of HGH!)
and time keeps on ticking.

That said, people like Lance and Dara Torres are bringing quite a bit of
attention to 30+ year old athletes. If our nationals is any indication, things
just start to get better at 30 :-)
