I remember tasting beer a couple of times when I was little, and I didn't understand why anyone liked it. Alcohol still doesn't appeal to me. If having some periodically is good for you, I suppose you're missing out on that, but you might as well just eat well and exercise regularly, probably won't make a terrible difference and you won't have to worry about intoxication. If you have a family history of alcoholism, or you tend to overdo enjoyable activities, it would be prudent to pass on it; if you can use it legally and responsibly, it's up to you whether you want to spend the time and money on it. I'm about to finish my second year of college and get my Associate's, and I still haven't had anything to drink. I'm more outgoing, physically active and happy than I've been my whole life. If I'm missing out on something, I can't say it bothers me.
