Boxing is very bad for the health. Like heading a football, especially in the old days, when it was heavier, especially when wet.
Yes of course there can be brain damage... but again if you know you place and lets say based on your skills you just do amateur fights, don't close your eyes and put your chins up in the air (ahem brawl)... and just be safe... And in training again you don't go bang up... like you can use headgear & there is technical or (*soft*) sparring etc it can be fine for your health
I'm not a physically aggressive person. Most fights I've been in, and they're very few, I've consciously tried not to hurt the other person and ended up just agreeing to stop, probably in a slightly losing position. I only ever in my life challenged someone to a fight once and I can't even remember what happened. It was when I was about 13 and somebody came over one dinner time when we were all sitting in the sun on the school field, and told me there was someone who thought he could fight me. It was a rough part of the World and so I sent him back with a challenge, for honour's sake. I can only remember two occasions in my life, when I've been so angry I've tried to do maximum damage and it only takes two seconds. Those two incidents taught me that peaceful means are always better, so I believe that chess-boxing would not be very clever and, perhaps, even a bit stupid. Incidentally, would gloves and gum guards and whatever be worn?
Yea the whole thing; Mouthguard to prevent teeth from getting knocked out, hand wraps and 16oz gloves, maybe some boxing shoes, and definitely a Jewel Protector (groins). Well perhaps you don't want to fight etc and not resort to that sort of thing... but Combat sport is great for exercise as well some productivity in unarmed combat... Naturally only sports I follow
