>That reminds me, I heard/read something very interesting about the origin of vodka recently - can't remember what it was.
I don't know what you might be referring to - the Wikipedia entry explains the (possible) origin of the word, the history of the drink, its characteristics (basically, vodka only contains water and alcohol), and a few more details.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
