My father was a house painter. Back in the 1940’s, he mixed lead into his paint by hand. For about 5 years, we lived less than a mile from a coal fired power plant. The crap in the air was so bad from the plant that my mother could not open our windows.
My Mother made it to 92 and my Dad to 95.
I’m from Jacksonville, FL originally. I the summer we would all be out in the street playing kick ball about dusk and the air tanker would fly overhead at tree top level spraying DDT. We just ran up on the front porch til most of it settled then right back out on the street. Sometimes they would just send the fog truck around spraying it everywhere.
