Why did you start smoking?
I have honestly never seen the appeal: you pay through the nose to ruin your health and appearance while slowly killing yourself. So why did you do start? I guess I'm mainly asking about tobacco and cigarettes, but I'm also curious about answers for cigars, pipes, hookas, whatevers.
Full disclosure: I'm sensitive to smoke (not quite an allergy) and have never smoked, so I'm a bit biased.
