Very cool. Our
Sesei trains under someone (Gene Dunn) that learned directly from Henzo Gracie back in the day. It is an awesome art to compliment a good stand up game. People that make fun of guard, have never been caught in someones guard that knows WTF their doing :P Oh and Lugh, it's only gay if you make eye contact

In fact, about any video of a competent BJJ practitioner vs X style, BJJ almost always comes out on top. Especially if there is no ground work in the others skill set, they just don't have the tools to deal with it.
You won't see me in the ring, but there has been a handful people from our Dojo that started up in local cage fights.
Team Karoshi has been pretty successful for just getting serious over the last year. It's cool to watch people you train with every week go out and beat some whole sale ass
Starting up Martial Arts is no questions asked, THE best thing I have done in my life. Would not trade what I have learned about myself and life from it for anything else in the world. Your brother should love it, I very highly recommend everyone go give it a try at least once. Especially women, the stuff learned in BJJ and other arts that rely on leverage and technique and not brute force could be priceless in an altercation. Don't get sucked into a McDojo though, do your research.
