I'm 44 and can attest that it's still fun even in middle age. I've only been a very occasional, infrequent smoker in the last couple of months as my sister's been dealing with a terminal illness and has been smoking to help boost her appetite.

I'm pretty certain her smoking days are now over, and mine are, too. I start medical school in about three weeks, and I think I have to sign code of professional conduct agreement saying I won't do illegal drugs as a physician in training. So I guess I've already said goodbye. Maybe when I retire I'll take it up again.
