I'm not sure if you were talking to me Jeff, but I said, mid to upper 30's, not just his 30's. There is a difference.
Statsitically speaking, athletes tend to show signs of wearing down around the age of 32-34 years old. It's more subtle for some than others, but it's a given fact that players wear down before 35. Barry Bonds power numbers increased.
He set the single season record after 35. I'm willing to bet that he's hit more homeruns between 35-40 then anyone else in league history, and probably by quite a significant amount. I don't have time to check into it, but it's a safe bet.

He became a power hitter in his mid to late 30's. That is unheard of in the entire echelon of professional sport.
