That's true, I should of said generaly more dangerous. I was making my assumption off the fact that to be a gym teacher (atleast here) you need to be physically fit. I think the likelyhood of a gym teacher being in better shape than a regular teacher is probably high since they're doing activities everyday. Of course this doesn't count for all people but atleast in my area accounts for most.
Haha, yeah, but it's definitely not an inherant fact.
My sister's elementary school gym teacher would yell telling them to run faster while taking another bite out of his delelctable Twix bar.
