Mr. Simmons,
I agree with you 100%!
people who are attracted to BJJ and NHB tend to be hot heads, fighters, drinkers etc... Like you said this is just **MY** experience. I am sure not all are like that, because I am not and I know others who are not.
But think about it it, someone comes in the Dojo and says they want to learn to fight ASAP. Hmmm.. Why? In my opinion, BJJ is a beutiful technical art, Nihon Jujutsu is beutiful all around, a life long study of depth and richness.
Anyway, I agree with your experience.
best,
-Rick
