I’m not advocating smoking cigars or cigarettes, but I will say that Winston Churchill smoked them most of his life, and lived to be 90. George Burns was also a cigar smoker and lived to be 100. Sometimes it’s down to the person.
I knew a guy that smoked 3-4 packs of Camel non-filters and drank like a fish. Shots of Kesslers with orange slices for a chaser. Lived to be 93. Asked my doctor and he said the problem with smoking is that you never know how it will affect you. Some people can get cancer in a short period of time.
