It's the same with sex too - I know 15 year olds who have had sex who are emotionally mature to deal with it yet I also know 25 year olds who aren't.

I completely agree with drinking at home - what I do in my own home is my business only and I don't want government controlling that. If I choose to get wasted, that's my choice provided I don't infringe on anyone else's liberties. I still believe that most ASBO damage from drinking comes from the people who are leaving pubs and clubs than those who drink at home.
