I don't smoke, don't drink much, and go to the gym five times a week. I live a healthy lifestyle and feel great. I can run a marathon, you know.
Boxing, for me, it's the beginning of all sports. I'm willing to bet that the first sport was a man against another man in a fight, so I think that's something innate in all of us.
I miss that sensation of a small achievement feeling like a really big deal.
