I think the thing smokers ought to do is make a twice-weekly visit to the pulmonary ward of a large hospital and just observe the patients there. That'd change their minds fast. It's not pretty to watch people in the end stages of smoking-related diseases.

Good for you for not smoking, Tallulah! I wish everyone could be persuaded not to do it. It's such an easy way to prevent premature death. And, for that matter, to prevent premature aging, too.
