me I've done not much to other people, broke a few noses, kicked out a guys teeth (by accident), disolcated a guys knee (horribly painful, but not life threatening ever), some other mosh damages in the stage diving and well, moshing departments.
Had a guy smash a brick over my head once, a random attack from behind as well, not only did I magae to not fall unconscious I stayed on my feet too, which I think surprised both of us.
I had plenty of mosh stuff happen to me, stage dived, and got kicked in the head which due to a horribly low roof meant Imy head flicked back straight into a beam, my forehead was swollen for a while. smashed my head into the floor via skateboarding/bullies and got punched in the chest which burst a blood vessel in my lung, coughed up blooded for a few days after that. I broke my ankle as well and could still walk on it which was beyond stupid.
