I quit smoking and it was 20 years ago to the day on March 11, 2020. It was, hands down, the hardest thing I ever did. I was up to 2.5 packs a day when I quit; my mother, who died of complications from COPD, was smoking more than a carton a day when she went into the hospital for the last time, so I certainly had a genetic inclination to become highly addicted and it didn't go unnoticed when I gave it up. But give it up I did, and I lived to tell the tale.
Yes, it was a very different world back in the day. We could smoke in theaters, in airplanes, in restaurants, in stores... I remember going into one store and being admonished that I could only smoke in the tiled areas, not in the carpeted ones. I was one that had to have a cigarette after a meal and I'd smoke it at the table and I didn't care what dirty looks I got.
Man, times have changed, and so have I.
