I think it should probably be lowered to 16 at least.
But I have to say I loathe the way the media stereotypes under-age drinkers. Did me and my friends (and most people I know) spend more Friday nights than we can recall sitting on a bench with a bottle of vodka and a few joints? Yes. But I'v never knowingly intimidated anyone or tried to physically harm someone, nor have most under-age drinkers from what I can tell.
Now if you think public urination, poor singing and vomiting on the street are serious problems, I haven't got a leg to stand on I'm afraid.
Frankly I don't think we could call Britain 'Great' any more if we lost our drinking institutions. Personally, I want to see people falling over and I'd be greatly disappointed if I couldn't go out and hear a slurred rendition of Wonderwall in the middle of the street whenever it gets dark.
And what, really, is the point of drinking but never getting drunk? It's a drug, if you don't effect then it's pretty much pointless.
I swear some of the ideas the government are cooking up are insane. Smaller bottles? If someone's buying 3 litres of cider it's because they want 3 litres of cider. If that comes in one bottle or ten, it doesn't really matter. And now the Tories want to up taxes to something ridiculous like an extra 50p per litre. Yeah, cos we're not paying insane amounts of money already.
The government should tell me the facts about my products, enact and enforce laws to stop me hurting other people and then leave me the hell alone.
