Concussions and the kendoka

[b8amack]

FWIW, I have never actually seen a concussion from kendo, nor do i know anyone who's had one.

I have seen. I also think I know what the OP means by how he (I assume... guess I'm just sexist) may have received one. If someone goes for a short men and hits low, they sometimes essentially tsuki your forehead, right above the mengane. That gets your brain going back and forth in that "easy to get a concussion this way" style. I've had it happen to me (I'm sure a few of us have) and it can be unpleasant. Men pads do absolutely nothing to protect against this sort of hit. And for jj, tilting your head so you receive the blow on the mengane? Bad idea.

Personally, I think the OP should think about listening to all those doctors. If I ever slept for three days and couldn't talk in coherent sentences after a kendo practice, I would quit.
