There are some possibilities for non-concussive unconsciousness without significant brain trauma- strangles (sleeper holds, vascular restraints… there are a lot of euphemisms)- the person goes out for twenty seconds plus, and unless there is a pre-existing condition (heart problem, arterial plaque or blood vessels weakened by excessive drug use) there are no ill effects. –Rory Miller
Friday evening BJJ in Bellevue. All spars.
Sat: I had lofty plans of BJJ followed by more yardwork, but my car died on the way to class. So I ended up spening the afternoon hiking across Bellevue to the Rent-A-Wreck instead. Missed class, and when I finally got home, it was raining. The day was a wash.
