Bruno does not appear to be aging. Despite his apparent mental troubles, he clearly looks after himself well. He looks in great shape for his age.

I rewatched the 2nd fight with Tyson recently and it was a shame Bruno didn't know what to do. There was no jab and in a panic every time Tyson would rush in all that grappling.

It's a funny one, he boxed excellently against Lewis and won many of those rounds. He could box, but I guess Tyson is a scary man once you are in there with him.

Lewis is someone you have more time and less nervous energy to burn against with him being far slower than a still dangerous period Tyson.

Tyson was a bit like Manny in that he can take a punch and always beat the other guy to the punch with excellent speed and smarts.

My post meandered. I apologize.
