From my experience, people who are mellow and laid back tend not to smoke. Very active athletic people tend not to smoke. People who are fussy about their clothes and surroundings, where they want everything neat and precise, tend not to smoke.
This is just in my observations. I'm not saying that people who smoke are nervous, lazy or messy. Okay?
My main problem with featuring smoking in movies is that I do believe it has increased solely because of contributions from the tobacco companies in their effort to get more people to begin smoking. Smoking is not good for anyone's health.
Now I've got to go to work.
