My freshman health teacher was a WW2 combat vet that enlisted after Pearl Harbor. He’d been drafted by the Rams.
Yeah - same here. My freshman health teacher was a Vietnam Vet. Was a PE teacher, and baseball/football coach (when they used to not overlap). He always told funny non-combat stories about things he saw in Vietnam. The discussion on VD included experiences of his "buddies" in-country. Better and more convincing than any text book. It was an all-boys school, so he could be more graphic.
I am certain, teaching health was NOT one of his interests/goals in life.
