Yeah, like someone else said, it's not really relevant to anything. I have friends who train at other schools and in other states, and when we get together it's like "finally, we have someone in our normal life who can relate to jiu-jitsu!". My wife likes to hear about it, because she's supportive of me and she thinks it's fascinating. Otherwise, no one I know really understands it, so they either don't care or they make jokes about learning to kill people. That's cool with me, I'm not in it for the glory
In the same vein, for work I'm a recording engineer. Like bjj, audio production is a very technically deep combination of art and science. It's easy to do incorrectly and takes years of practical experience to do well. It's difficult to have good conversation around it because most people just don't know anything about recording music, even the musicians I deal with. So I get really excited when I'm talking shop with another engineer, because I rarely get to speak that language in my day-today interactions.
