Programme on BBC 1 Scotland tonight about whisky. It's part 4 of a 4 part series about addictions to pleasurable stuff.
"Addicted to Pleasure: Whisky.
Brian Cox [not the physcist] delves into the history of Scotland's national drink, revealing its origins, the rise in addiction in the 19th century and what it did for Scotland's reputation".
It'll be on the Iplayer shortly (just being broadcasted now) but bit convoluted to find it but here's a link to the series and it should be on soon. When it's updated, I'll edit the link.
