I think it is the result of a cocktail of memories, education received, nostalgia and other events of our childhood and adolescence. I am referring to the generations that come after us. From those who were born in the 70s, 60, 50, 40 to back.
We watched TV, and everybody smoked, in the programs, in the movies, our fathers, mothers, siblings, the milk delivery man, etc. For me in particular, when I'm not at peace, I find it hard to smoke, it's not a pleasant smoke, even with my favorite tobacco. Or reading a good book, or even a good distillate. I need inner peace.
