Why do people smoke, when they know they will die more quickly?
Actually, I think your conclusions are unfounded. Now, mind you I am not defending people who smoke as I think it is a really disgusting habit, but on the other hand, you might think about doing a little bit more research on the basis of people contracting second-hand smoke, as well as lung disease before asking questions such as these. I am acquainted with people who had been around people who smoked for almost all of their lives and they eventually got lung disease, or emphysema of the lungs and what have, while the actual SMOKER is still alive and kicking to tell the tale of it. I just think you should do a little bit more research before you judge someone prematurely.
