I've been looking into boxing for a while and am pretty interested in it. It's one of the more interesting combat sports in my opinion.
My question is, what sort of effects does boxing have on your brain? I know getting hit in the head isn't the most positive thing for your brain, but I'm wondering to what extent you can sustain damage, both short and long term.
I'm obviously not going to be a professional boxer and may not even compete as an amateur, but what effect does serious and consistent practice and sparring have?
Any links or first hand information/opinions would be appreciated.
