Am I reading that right ?Bernard:
At the time my teacher was developing as a martial artist, he was more likely to have to defend himself against a police officer, who held a position of authority over him - both vocationally and racially (the race part does have implications). Or he was equally likely to have to fight in a small elevator or stairwell in a tenement building as someone would be trying to "mug" him. I don't think people get mugged much anymore?!? Point being his combat terrain and circumstances were much different that those of his primary teacher who was from the pacific islands.
Today my students and myself are more likely to encounter a ground fighter, or MMA practitioner. As we all well know, our surroundings have changed, there are little to no warrior codes/ethics around which combatants do battle, different motivations for would be attackers, and less accountability systems for warriors to adhere to. All of these things affect our fighting realities, and not many people in my experience are energetic enough to study into AND PRACTICE what it takes to remain relevant.
Do you mean you are likely to encounter a BJJ or MMA guy entering the gym to test his skills or that you are more likely to be attacked by one on the street than a mugger ?
