Got to love British humour. I enjoyed this one not least of which because I used to be very firmly in the camp to the teetotalers. Looking back I think that it actually isn't a particularly healthy attitude to treat drinking alcohol (in an of itself) as some sort of horrible sin. Working as a criminal lawyer I certainly see the terrible fruits that too much drinking bear, but I wonder if this isn't due in part to the prevailing attitude on drinking that (as with smoking) there is something inherently wrong about it.
In the Middle Ages people drank a lot of alcohol; wine was, for all intents and purposes the principle drink of that period, with beer and mead being seconds. It was consumed for pleasure and as a medicine. People of all walks of life would frequently drink posset (boiling wine and curdled milk) before bed. Yet I've come across nothing that would indicate alcoholism or degeneration were a problem (see Medieval Famines, Bread, and Wine at Tradition in Action for more)
Well, this is getting a bit deeper than my infrequent musings usually are. Maybe, simply "everything mankind does is much, much easier if you're ever so slightly drunk." A snifter of Brandy (as pictured in my introductory post) certainly never hurt the flow of the creative juices when writing.
