Yes and the police reports and the questioning all night long are something I have not done in a long time and do not look forward to doing in the future if I can avoid it. I will say this most were just an over night stay. A couple were a little longer as they were unconscious or just coming around when the ambulance took them away. Getting dropped on the asphalt or having one's head meet a wall or car does that. I will admit I spent a few hours getting tests or xrays done myself. Other times when I should have gone, I did not, or went to the doctors a few days later. In training I have separated someone's shoulder. I have had a rib "pop" out and back in no break, just the loud popping sound I felt the motion and saw a blinding white light and lost all my air. I guess miss blocking a spin heel kick by an inch will do that. I have broken fingers (* happens with sticks all the time *) and I used to carry a frog just for that because of the accidents that can occur.
