Getting into an altercation in “real life” is going to be much more dangerous than say something you’d see in your kwoon or in an MMA competition. There are so many uncontrolled and unknown variables that can present themselves, and as such there’s not going to be one fighting theory or maxim or rule-of-thumb that you can adhere to except maybe the one that says to stay clear of situations that may result in you getting into trouble in the first place.
For example, let’s say you’re at a shoddy looking gas station with some dudes sitting out front and one guy comes up to ask you for a cigarette. To which you reply you don’t smoke. Then he asks you for some money for a hamburger…to which you reply you don’t have any to spare.
Already at this point your internal alarm should be going off telling you that something’s awry. You should be aware of your surroundings, giving yourself space between you and the guy, and turning your body a little so that you’re at an angle to him. He then says in a more frustrated voice “I know you have money…you’re about to pay for gas!” He steps towards you a bit…what now?
To illustrate this, do you:
A. Preemptively chain punch his face in until he hits the ground and then flee?
B. Tackle him and go to full mount and then attempt to choke him out?
C. Stand your ground and wait for him to actually attack before you do anything?
D. Let him know to “take it easy and that you don’t want any trouble” while moving back?
"I don't know if anyone is known with the art of "sitting on your couch" here, but in my eyes it is also to be a martial art.
It is the art of avoiding dangerous situations. It helps you to avoid a dangerous situation by not actually being there. So lets say there is a dangerous situation going on somewhere other than your couch. You are safely seated on your couch so you have in a nutshell "difused" the situation."
