Recently, I've found when I roll, after we begin and someones got me in mount or side control etc, I seem to close my eyes until I get on top again. Subconciously I must think it makes me concentrate better, and make me a better grappler. I do this alot also when people begin to get submissions on me, particularily chokes. I think it helps me stay calm, but I don't really notice myself doing it until I get out of whatever I'm in and start over. Does anyone else do this? Or any other weird or funny habits?
