Over here in the UK, the drinking age is technically 5.
Below 5 your only allowed medicinal (sp) alcohol, above that you are allowed to drink on private property with your parents permission. At 16, you can have a cider or glass of wine with a meal, and at 18, you can drink until your hearts content.
I believe an 18 year drinking age is perfectly fine. Suits everyone around here, and makes turning 18 even more fun, as your legally allowed to get pissed, hell, it's almost a legal requirment
I don't agree with a younger drinking age. I know kids will always get drunk underage, but letting them in bars at 16/17 isn't good. An older drinking age is just silly, like people have said before, you can drive, get killed in the army, your a full adult, but you can't legally get drunk? Bah!
