If you stop and think about it, alcohol is just the worst. Almost every one who drinks has experienced the pain of a mean morning hangover (at least once). Also, the experience of being drunk… why is that enjoyable? When drunk you slur your words, it’s hard to think straight, you’re liable to say or do something that will offend the people around you, and you can’t legally drive a car. Why does any of that sound like a good way to spend a Friday night?
To a sociologist, the reason people drink alcohol is that they have been socially taught to.
