I see it the same way as Jane Emily: Karate aka Martial Arts, but to add. Mind you, as transgender individuals, not everybody is understanding of us, so below is my mental checklist I go through everyday(i.e. After awhile you can go through your mental checklist in 5 seconds or less):
Situational Awarenss: Know your surroundings(Area of Operation) and what your getting yourself into, environmentally wise, with loved ones, friends, neighborhood, strangers. AND KNOW YOURSELF(i.e. Your internal awareness): What is your present physical/mental state?, Are you up to it? What are your preparations?
Mission: What is my mission for the day, to just get some sun at the park, to go coffee/breakfast socializing with friends/loved ones, grocery shopping, clothes, car parts, kitchen appliances shopping. All require different avenues of perception and interaction with your environment.
Exit Plan: What are you thought out plans if things get bad for you and how will you evade and escape? Ingress and Egress points?, your physical conditioning to sprint, run, tackle.
Last Dance Protocol: What will you do if your stuck in a situation where your physically accosted with fists, knives or a gun? Do you have a plan and how will you react? Your combatives/martial arts skills.
I think about this daily since I live in the rougher parts of South L.A.
