Smoking is harmful, but I suspect it affects diferent people differently. Some will get emphysema and some won’t and while it is harmful to all, many live long lives.
My mom died of cancer at 47, lived healthy, never smoked. Both my grandmothers smoked into their 80’s and died in their mid 90’s. One grandfather died of a heart attack early, the other in his 80’s, a pipe smoker.
Based on historical analysis men who smoke a pipe live longer than those that don't. That is likely because they tend to be wealthier however who's to say their extra wealth isn't the result of contemplative pipe smoking and less time with other vices such as drinking. Smoking a pipe is an enjoyable way to rebel against the nanny-state Nazis.
