Wrong.
Current conventional common wisdom: smoking.
I made a curious discovery a number of years ago, perhaps 10 or so years past: in a discussion similar to this one there was a list of the modern 10 longest-lived persons, and their documented age.
All of them smoked most of their lives, with three of them smoking past age 100.
Ironically it occured during the "smoking" hysteria and the monumental penalty extracted from smokers in the U.S. via the tobacco companies.
Before all of the smoking hysteria, my father was in a nursing home. I’d go over for cocktail & cigarette hour. The nurses used to ask me if I’d watch several others as well - they weren’t allowed to smoke unsupervised. There were 4 of them - my father was the “young one”; he was 90. The oldest was 102.
The nurses used to say that once you get to be that age, you should keep doing whatever it was that got you that far.
And, yes, that nursing home bans smoking now.
So the heart didn’t stop?
