I simply have no desire to drink alcohol, in the same way that I have no desire to drink coffee. Its just something that I dont care about in the slightest.
21, of age, don't drink. I've tried lots of different alcoholic drinks, and none of them tasted nice - I like grape juice but not wine, orange juice but not, say, Reef, and toilet cleaner over WKD Blue. Eventually I worked out what it was in the taste of alcoholic drinks that I didn't like - the alcohol.
Plus I can't drive my Mini when I'm drunk, so why would I want to drink anyway?
