1940s Hygiene

While discussing banned pesticides, my professor said that as a schoolchild in the 40s, he and his classmates were sprayed with DDT.

Yes, I did say DDT.

A truck with DDT arrived at his school after a breakout of head lice, and everyone lined up for a dose of poison that can't even be sprayed on crops today.

He seems remarkably blithe about the whole thing. "Nothing happen to me . . . It was a good experiment."

Yes, this is the same professor who used to wash his hands in benzene.
