I don't think drinking alcohol anything wrong. It's almost always acceptable if we control it in a moderate way. There are many stories talking about extended longevity of people who used red wine per day. I think that's only one of the factors to help people live longer. There still exists other numerous ones giving great impact to human life such as: living condition, good atmosphere, sober drinking and eating, good mind etc..However, a prolonging life-span without joys would bring no poetic flavor for life as well.
On my part, I don't like alcohol much, but a little beers in jolly meetings with friends.
