I smoked two packs a day for 34 years, so you could say I was an addict. But this addiction had many benefits for me. Something no one talks about! It calmed me, it helped me concentrate, it was a good weapon for coping with unexpected challenges.
So, as a cigarette addict I would never have felt aggressive toward anyone who stared at me. I finally quit in 1990 because some of my Baptist parishioners didn't care for their pastor smoking. It was the guilt, and a lot of prayer, that helped me quit with relative ease.
But one of the side effects (at first) was a marked crankiness, it was so bad that my daughters begged me to go back to smoking! That's where your aggressiveness comes in, HD!
As an aside, during a routine examination, five years after I quit, the doctor checked my breathing capacity and couldn't believe that I had ever smoked! I haven't craved cigarettes for the past thirty-three years except, strangly enough, only two weeks ago when I watched an old movie and felt like grabbing the cigarette right out of the actor's hand and smoke it! Strange, not a twinge for all those years and then that!!!
