Just my opinion... Try voiding unstable environments. Do not act as if you are scared, even if you are! Fear is natural, but do not allow it to overcome you. Do not look like pray, but do not look like a threat. If you are approached keep your distance and keep your back away from them. Always carry a weapon, if it is illegal, carry a box cutter in your pocket. Act like a complete psychopath! Example being, I will freaking cut your throat out, and eat your freaking children(and that is being nice)! If it looks like it's going to progress strike first! Strike at 45 degree angles, circling away keeping your enemies in front of you.
