in one of the pieces linked here on the new mouthpiece studies related to concussions, iirc women's lax was very high in concussion rates (football, women's lax, women's field hockey?)

Field Hockey!  Big on the East Coast, so let me explain.  A bunch of women looking right at the ground, hunched over slightly to get in a better position to whack the ball.  You get two women running at a good clip but with their heads down watching a ball on the ground.  Since their heads are literally leading the way, it is all set up.  Then Bamm!  Their heads collide.  Noggin v Noggin.  Putting the hair up in a pony tail does very little to protect the head.  It happens, and like in many sports wearing head gear is kind of uncool.
