I did an annual football game with friends for years called the christams bowl. We'd play full contact, no pads in freezing cold weather every year around Christmas since we were like 12, same core groupe of guys. That was up until about 2 years ago. First someone got a broken nose, then an arm. The next year a concussion and a dislocated shoulder. We realized that grown men can't smack the shit out of eachother like when we were kids...Good times though.
