I smoked from 17 to 34 yrs of age. I, like most of my family of origin, quit after my grandad died of lung cancer. To see someone she loves smoke made my grandmother cry after that. You go to my family reunions these days, my cousins, my aunts my uncles, all quit. It is a stupid habit. I know a doctor that wants the death certificates to have a check off box to replace Lung Cancer with "Died of Stupidity"
