My old man is over 70 now, lifelong smoker. One of his first jobs in his mid-teens was breaking up asbestos lining in steel moulds/pipes, and he sometimes tells me of the slew of now-banned chemicals his old man would use around the home, e.g. IIRC, some kind of pest detterent powder he would sprinkle handfuls of in the pantry, which was some variety of DDT. It's crazy to me that he's still going; I still expect a call some day, "well, turns out it's got me".
