Self defence breakfalling

This is just a quick comment on break falling. Last week when training nage komi (full throw repetitions) my partner was on the receiving end of a harai goshi. As he broke the fall by slapping his LEFT hand on the mat, he gave no thought at all to his head. As a result his head hit the floor pretty hard and although it was a matted surface, he still was slightly dizzy from the fall. Two little pointers regarding head guarding,

1. Always keep your chin tucked in, mouth shut and tongue pressed against your top jaw.
2. Use your non break falling hand to cover the side of your head so if you does lose control of your head it will be your hand that you hit rather than the floor.
