I actually miss the days when characters smoked all the time. Smoking did look cool back in the day, despite the fact that Humphrey Bogart and all those other actors died of lung cancer eventually. There is a hilarious scene in the original The Day The Earth Stood Still in which a bunch of doctors are marvelling about how a humanoid alien can stay so young looking yet be so old. Whilst popping out for a cigarette break, they speculate that the aliens must know something they don't.
