Amazing stuff, despite the loss...Shane Mosley...amazing! To be in this kind of conditioning at 40? Yep, amazing!

(edit) Go to around 50 minutes to watch the last 2 rounds. Before the fight, few thought it would go the distance.

Boxing is a peculiar sport. George Foreman came back in his late 40's & beat up some guys. Archie Moore had a go with Ali, I believe in his '50's (no one is sure when he was born). Didn't go well, but I think Ali felt the sport owed Moore a real payday.
