Don't worry - us oldies also got up to mischief so it's not a recent thing. I was in pubs at 13 - not a lot to do in our town! But I'd only ever have two drinks and thought it was ridiculous when my peers would write themselves off at parties. I don't think it's about age, it's about why people are doing it. I was actually a very responsible drinker pre-18 because I was around friends and didn't need to prove myself. Then when I went to uni with a whole bunch of new people, different story and although it was now legal, I drank STUPIDLY because I was shy and booze was a way to control my nervousness.
