I am also about the same age. When I was 12 I moved to DeKalb county Georgia. I was one of the biggest kids in the grade and everyone wanted to kick a yankee's ass. Six ,months after we moved there, my Dad died of pancreatic cancer. We stayed for a couple of years, long enough for a kid to develop a southern accent, then my mom wanted to move back to Mass to be near family. Same story, only in the reverse. Wrestled, football and martial arts. Also, might have attracted some attention from the local girls, which didn't exactly thrill their boy friends. When I was in 10th grade, I got into a fight with the toughest kid in school, Johnny Dutton, and I swear, at least 200 kids showed up.
I also have a fraternal twin brother who was a year behind me in school, looked nothing like me and was a real skinny kid. The black kids in Georgia hated him, and every time they beat his ass, I would stand shoulder to shoulder with him and make sure they never did it again
I graduated high school before I turned 18 and left for Marine Corps boot a week after. I turned 18 on the Island. There might have been a few altercations as a Marine. Whenever something happened, I was the first target. They always go for the toughest guy first, and usually not alone.
When I got out of the Marine Corps, I worked nights as a bouncer at a pretty active night club in Weymouth to earn extra money. Anyone remember the Bajabeach club? LOL. It wasn't exactly Road House with Patrick Swayze, but something happened nearly every night and more than a few nights guys that got tossed came back at closing.
I don't drink, hang in bars, and in my whole life have never walked into a bar just to order a drink. Not even in the Corps. Sorry for the long response, but you asked.
