Being involved in Martial arts for a long time, I was routinely punched and kicked in the face.
10 years of serious competition, I have been concussed a number of times, mostly before we found out what was happening to us anatomically from head shots. I had concussion symptoms and ignored them, I had Cerebral fluid running out of my nose once, its bright yellow, and scary.

I had too much trouble in bars so I kept away from them for the most part, then found out work was a good place to get into a scrap too lol.

I haven't competed in 25 years, but I am still involved through instructing others.
The last time I hit anyone was 20 years ago, open hand slapped a guy, he went down and then he shut the fugg up.
