I know some people say they hate when people call bjj therapy. But that 30 is 60 minutes of rollling, where you can't think of your problems. Because you have to be in the moment, and deal with the guy on top of you trying to choke you. There's definitely something therapeutic about that level of presence. And maybe that's the only time most of us find that, insane level of being in the moment. Without obsessing over llives problem.
