I think 1 thing most of us martial artists have in common is a certain paranoia and ability to anticipate danger and aggression, before it happens.

By paranoia I mean, when going somewere I am always aware of my surroundings In my mind I size up the people I encounter and on a night out I always have my eye on the idiotic group in the room and steer clear.. A lot of times I keep a subtle but solid base as well as keeping my hands up as I gesture while talking.. Just a few subtle ways to be prepared and makes me feel comfortable
