This is a good time of year to talk about uplifting spirits. I speak of the alchoholic variety rather than the religious! Drink has been enjoyed since time immemorial by civilisations around the globe. Of course, before I am lambasted for being irresponsible or insensitive, it has also caused illness and misery and is often behind violent and anti-social behaviour. But for many it has proved to be a welcome social lubricant associated with conviviality, friendship and pleasure.
