Even Brady... as much as it grates on me to admit it.

I constantly played sports until the age of about 35... after that I still played, but sparingly. I had moved on. That same old drive to compete had waned. So I can't even imagine playing at a 'pro' level, with the commitment in passion and physical prep that that level of play requires, into your 30's... or hell, even into your late 20's.
