Relatives who drink
My mother is 90 and had a pretty bad drinking problem when I still lived at home. She got it under control somewhat but still has (I estimate) 3-4 Vodka martinis every night. More on holidays. Her doctor once told her she was the healthiest old woman he'd ever examined. She's very active for her age. My great great grandmother had a laudenum addiction when she was young and drank whiskey til her death at the age of 92. She had to be physically stopped from going to the dance hall/bar down the road by my grandmother who also enjoyed her vodka until her death from colon cancer at 82. I don't know what I'm getting at here except to offer hope to anyone who worries about their medical issues after drinking. Sometimes you can survive a lot of abuse before getting better. I wouldn't count on it though. I don't know. This is probably not helpful.
