This documentary is about the jiujitsu lifestyle in So Cal. It starts old school, back in the day, when the Gracies were new to the US and teaching out of a garage.
I also recommend the video below (great little fight at the beginning, ending in a heel hook; you can feel the adrenaline). I never liked sport jiujitsu. We always rolled as if the other guy could throw punches, even if he wasn’t.
Stephen Hsu is vice president for Research and Graduate Studies at Michigan State University. He also serves as scientific adviser to BGI (formerly Beijing Genomics Institute) and as a member of its Cognitive Genomics Lab. Hsu’s primary work has been in applications of quantum field theory, particularly to problems in quantum chromodynamics, dark energy, black holes, entropy bounds, and particle physics beyond the standard model. He has also made contributions to genomics and bioinformatics, the theory of modern finance, and in encryption and information security. Founder of two Silicon Valley companies—SafeWeb, a pioneer in SSL VPN (Secure Sockets Layer Virtual Private Networks) appliances, which was acquired by Symantec in 2003, and Robot Genius Inc., which developed anti-malware technologies—Hsu has given invited research seminars and colloquia at leading research universities and laboratories around the world.
