Ditto on 82, mate.
My Dad passed of similar stuff at 82..
2 packs of Camel straights for 20 plus years and getting his chest crushed in a farming accident didn’t help either.
He used to tell about the young doctors and the stuff they did when he had a deflated lung.. he always had bronchial problems, asthma.. he was running on fumes at the end tho. cardiopulmonary failure was the end result even tho his heart was strong.
I remember when my father was at the VA doctors office about 3 months before he died. The Doc looked at him and asked he ever thought about quitting smoking. My dad looked right back at him and snarled “ did the Army ever think about not giving me free cigarettes for 30 years!”
The Doc just nodded and walked away
