Does anyone know? How to connect these two?

I honestly don't think there's a connection at all. All sorts of people are attracted to karate. It really has something from everyone and different personalities enjoy different aspects-- be it the sport, the art, the camaraderie, the technicality-- whatever.

I personality am an INTP. I like the individual challenge and breaking down the moves, though my lack of attention to detail in actually performing them hinders me. I also like learning the history and differences between arts. I'm not that into the sport part of it or the dojo drama (but luckily there not much of that at my small dojo).

When you fight in 'high heavenly stance' which is a term i've coined for arts like boxing where the legs are appromaxitly straight (Ni, Si). Being introverted is being tall, N/S are legs, used for running. Like a buffalo escapes from a lion. But high heavenly can't run as a big cat because it doesnt have endurance. However, when the legs are straight, the arms are lifted up making it stronger muscle-wise and then the arms provides 'control'. A big cat has control. But a buffalo, not tall a dwarf can kill a lion if it goes head on because it has a powerful strike that could possibly break through control defense.

P is striking hard with fast legs and low defense. J is great control/defense but lower striking power.
