As a non-smoker, I really don't understand why people smoke in the first place. I have friends that have told me that they had self esteem issues when they were young and smoked so that they would be perceived as cool. I have other friends that smoke but they never completed high school so they aren't very bright. I asked my great grandmother why she smoked and she said when she was young, no one knew that smoking was as dangerous as it is and that the warnings didn't come out until the mid-fifties. I think most of the people that were unaware of the overstated dangers are dead by now. My great grandma is still alive but she lives in an iron lung. On the other hand, I completely understand why people grill and why they drive cars.
