Quite an exciting iaido practice. about 30 minutes in, a girl who had come to check out iaido was sitting quietly on the side, when all of a sudden she let out a little moan, her eyes rolled back, and she fell sideways out of her chair. Everyone ran over and she was shaking like she was having a seisure. I grabbed my towel and someone put it in her mouth and held her down so she wouldn't smack herself into the floor too badly. Kanae-sensei grabbed her cellphone and ran up to call an ambulance which arrived about 10 minutes later. By then the girl had stopped shaking and seemed to be sleeping, and when the paramedics came down she was awake and could stand up and walk out by herself. Not sure if it was a seisure or if she just passed out (freaked out by stress of sitting by 15 people swinging swords?) but anyway practice was strangely relaxed after that as everyone gave a big sigh of relief that she seemed ok. As for my towel, it was covered in blood (I think her mouth was bleeding a bit) and sacrificed to the greater good, so sensei said maybe I'd get a Suimokai towel in exchange for my quick action.
