Protect yourself at all times. It's what I talk to school kids and college kids about when I do my seminars. I'm not just talking about in the ring. Protect yourself at all times.
To me, you can be young in your mind, in the way you think, but if your body don't come with that, then it's wishful thinking.
The worst damage a person - a fighter or even a person that's just everyday living - is shorten your life by your lifestyle.
Hand-eye coordination and reflexes is something I work on more than anything.
When you get older, the first thing that starts to go is reflexes, and reflexes are important for any person, especially an athlete - to react to something in a time when something is going on, and you can't be a second or two behind.
I have to constantly work on my reflexes and hand-eye coordination. I do a lot of puzzles. I play chess.
