I have noticed that a lot of fights occur in certain places. If you avoid the places, you avoid the fights. Of course this leaves you still vulnerable to random acts of violence, robbery and rape, but it drops the chances of a violent encounter dramatically. I was kind of used to seeing fights every week in a couple of my then regular bars. The bars had loud rock music, lots of bikers and drugs, etc. Later I didn't go to bars that much and when I do, I go to the nicer ones where bikers are not so common. Now I have noticed that I haven't seen a single fight in at least a year! The last time I was in a fight, was summer 2001, I was very drunk but had to defend my sister from a robber. The robber was obviously completely stoned and didn't feel anything I got through to him. I had to run after my sister was safe.
