In my family, sort of the opposite.
My paternal grandmother lived well into her eighties, and so did her sisters. Her baby brother, who was wounded at the Battle of the Bulge, is still around and in good health. Don’t recal if he smokes, but Grammy smoked like a chimney and her sisters smoked. Her parents lived until her Dad was 93 and her Mom was 88. However, my grandfather dropped dead from a heart arrythmia that may have been exacerbated by smoking.
My maternal grandmother also lived well into her eighties, and her Mom died at the age of 93. But my granddad died much earlier (heavy smoker) and only after suffering for more than a decade with lung problems. His sister, a non-smoker, lived well into her eighties.
This anecdotal evidence seems to me to say that some people have a long life span and some don’t, that there are some lifestyle factors, and smoking creams some people quite badly while letting others off the hook.
It would seem to me that means there are other factors involved. Maybe its not the smoking at all.
