Used to fight a lot when I was in my late teens, mostly Football matches against other supporters, early 80's, Also had a fair few straighteners as in 1 on 1s, lost some and won some, against a few guys who were considered "Hard" Funniest one was I got one punch knocked out by a guy I never knew, found out who he was where he lived, went round that night and asked for a rematch.. He beat me again, thankfully no knock out the 2nd time lol, ended up good mates soon after.
Last straight fight was when I was 40, dropped a guy in work who was basically a bully always picking on lads, he squared up to me, I didn't talk just butted him to the floor and and pounded him a few times, Everyone seen him cry like a women so burst his hard man bubble.. lost me my job of ten years though so not a good outcome.
45 now and a lot less direct, (think before I act) plus the fact i'd last about 2 minutes in a real extended fight.
Some people only understand physical persuasion, it's never the best option but in certain circumstances it's sometimes the only option.
