Lots.
Made the "Police Blotter" a couple of years back when I beat up my neighbor.
I realized quickly that I was too old/out of shape to fight. I had to end it quickly.
My motto now is on this shirt:

Just remember,
"I ain't as good as I once was, but I'm as good once as I ever was."
Damn...when I was a kid, (grew up in an Italian neighborhood in Springfield, Mass) we'd fight out of boredom. Not exactly "fight club," but just about every day we'd fist-fight. Sometimes, there'd be 2-3 fights going at the same time. We (usually) didn't get mad at each other, it was more like practice for when we REALLY had to fight.
There were no boxing clubs anywhere in the area or other outlets for our aggressions, so we took it out on each other.
Served me pretty well over the years. I never backed down from a fight, no matter how big the other guy was...and I rarely lost a fist-fight.
Studied Taekwando for 2-1/2 years until my sensei determined that I was "going down the wrong path" and kicked me out of the class...so I found another teacher...one who taught multi-discipline self-defense. He said that in a fight, you should never hit the other guy more than 5 times.
Twice (at the most) to knock him off his feet, once on his way down, and twice while he's on the ground to make sure he doesn't get back up.
Hand-to-hand combat in the Marine Corps was lots of fun for me....:biggrin:
Even though I was a small guy back then, (5-6" when I enlisted) I only lost one sparring match when the other guy, (over 6' tall) managed to carry me out of the ring...for a win...but he was bloodier than I was at the end.
Spent a bit of time in the "county cross-bars hotel" and fights were pretty common in there as well...usually over stupid shit...but you gotta stand your ground and defend what's yours.
It's nice being a quiet docile old fart...I haven't had to fist-fight in more than 30 years...although I still don't take any shit from anyone...except my wife...who always wins.
