I think we should all observe a moment of silence for those poor men who taught in our nation's schools in the early seventies. These men, young and old, had to stand before hundreds, perhaps thousands, of young women wearing obscenely short skirts pointed at them day after day.
I'm sure many just splashed themselves with cold water between periods, others I assume were driven to drink. Thank God teachers could smoke in class back then - it took the edge off. With any luck, that job working for your father-in-law at the plant would work out, and you'd be free of this daily torture.... alas, for many, it wouldn't be so easy.
As a salute to the male teacher of the early seventies, here is a group of pictures dedicated directly to them. We appreciate your service.
