I am always amazed at how useful BJJ is. You can use it to change diapers or choke Pit Bulls. It changes lives for the better all the time. When a 9 year old boy can feel empowered enough to try a Rear Naked Choke on a attacking Pit Bull that says loads about BJJ.
I think we should teach BJJ in public schools. In fact, TheFightWorkPodCast has even done a few interviews on it. They are #154 – Jiu-Jitsu in Public Schools and Gracie Barra Donates Gis to Public School. It is my understanding that Kendo is taught in Japanese public schools. I’m sure other countries have martial art classes the students can take. I know I could have taken Judo at college. West Side Jiu-Jitsu, where I practice, got its start by teaching High School students for free after school. Mark talks about one of the success he had because of it in his post, The "Killer" Nerd. There are so many things out there that teach kids to act without thought and so few that teach them to be in control. I think BJJ could be great tool in our public schools for good.
