I am 39 and I don't drink, never have beyond the odd experiment in my late teens and twenties becuase I don't like the taste or enjoy the feeling of being drunk it just always makes me feel seedy and grubby and to be honest I just don't understand why anyone enjoys it but of course different strokes. Same goes for smoking and drugs it was just never for me, I prefer a nice cup of tea.
The issue is even now at my age the fact I don't drink seems to be an issue when I socialise and meet new people. I find a lot of men and women in my age group still drink a lot of booze and when they are drinking (most social events) they don't have much time for a non drinker or they assume I have perviously had a drinking problem. I don't mind anyone having a drink but its a bit annoying when I am regarded as the problem for not drinking rather than those who do. The truth is I think a lot of people, nice middle class professional men and women have borderline drink problems. I certainly am aware of at least a couple of marriges held together by the 2 or 3 bottles of wine they get through most nights. I can hardly believe it is socially acceptable for people to drink so much when smokers and fat people are treated like pariahs!
If anything many drinkers have a problem not me so why do they make a big deal about it, making faces and comments when I'm not boozing with them either that or trying to pressure me into drinking. I feel like giving up being sociable altogether!
