I've just started watching my DVDs of Goodnight Sweetheart - third time I will have seen it, I think.
A woman in 1940 lights up a cigarette. A man who has time-traveled from the 1990s says it is "very bad for your health."
She says, "Everyone knows they're good for your nerves. And there is no point worrying about a cough carrying you off when a bomb could land on you any second."
