Being a child during the 60s and 70s, smoking was a grownup thing, and almost all adults in my world smoked. I can remember times as a kid that I just could not get away from the smoke. Going on a two hour car trip to visit relatives seemed like torture. As I grew older, most my adult family members quit as did both my mother and father.
To this day, to me smoking a cigarette or cigar seems almost as discussing as eating dog turds from the yard. I have difficulty understanding why someone would voluntarily set a substance like tobacco on fire to breath in the pollution.
If you are a smoker, do the world a favor. Don't offer that non-smoker that first cigar or cigarette that may potentially get that person addicted and shorten that person's life.
