My grandparents smoked, presumably for 50 years before they passed in their mid-70's. They could have lived past 100, because my grandmother's sister lived to 103. But she also smoked for 80 years. My mother points out that unlike my grandparents, my great aunt was an avid walker, walked a few miles every day religiously. So she makes a fair point, because inactivity and sedentary lifestyles also are cut short. My mother's sister smoked intermittently, but ultimately had quit for 10 years before dying relatively young (58) from breast cancer. My aunt made the observation that cigarettes stink, but insisted that they did not used to stink, claiming that when she was young her parents smoked in the car with her and her siblings, and it never occurred to her to open a window, because the second hand smoke back then was not irritating in the least. Her brother, my uncle, smoked cigars, basically chain smoked them, died at 67. My mother smoked, but quit for decades, then started again and smoked for another 15 years before quitting again only a year ago. She's 79. Then there's George Burns, who started smoking when he was 14 years old and lived to 100 after smoking an estimated 300,000 cigars. See Ecc. 9:11.
Very sorry to hear about your uncle. How old was your uncle when he passed? What did he do for a living? Was he a veteran? How much did he weigh? Is there any history of cancer in the family?
> I only know people died from lung and other cancers or copd on a massive scale long before anything was added to tobacco.
If you could share any reference links to any study performed before the 1950's, then we could all know this.
