I've never been prone to anything like that, I've never had a seizure at all.
And nothing awful like that has ever happened to me at school, or anyone else that I know of.
Worst thing I can remember happening in school was in gym class in 6th grade, a somewhat overweight kid slipped and landed on a skinny kids arm and damaged it pretty bad, right before the summer to.
That same overweight kid almost broke my leg in fourth grade, we were racing back and forth across the gym and just as I reached the wall, he comes out of no where right in front of me and kicks off the wall to stop himself, and falls right back into me. I couldn't walk for five minutes, I thought he snapped to bone.
