just wrestle and don't get so worked up that you do something really idiotic or dangerous. Fist fights have the potential for far too much damage if you take them at all seriously. I've had fights just for fun with some of my friends and it's ok if you keep some sense in your head.
By the sounds of your original post, you were planning to go much too far
the plans weren't intended for that far :|
just like how you said it... for fun , my friends both found it fun when they did it and i thought it looked like fun so work it out
Some people have a brain, some don't.
Ive done my fair share of painful, dangerous and dumb shit in my life, but when you reach the point that you are endangering not only your self, but another persons life, then you have to stop and think real hard about what the f*ck you are doing.
if 2 adults want to bash their hads i think that there's nothing wrong with it.
IF they learn smthing at least ^^
AND wear at least some protection stuff. fightclub style is just a waste of vitality
