Drinking age - 18 or 21?

I'd say 18 because I was mature enough to drink at this time. Although, some 18 year olds are absolute morons (where I live anyways). To be honest, you should be allowed to drink when you're mature enough and not trying to drink just to get drunk and try and act cool.

 

If you need to be 21 to drink, you should have to be 21 to join the army or adopt a child. If they want to play that game, then they should be required to play that game for everything, not just things that are convenient for them.

As for the legality, how much underaged drinking is actually stopped by the law? All I know, is that where I live, EVERYONE drinks underaged. I've seen middle schoolers wasted.

 

No, it should stay 21 because the brain isn't fully matured until 24, and drinking before then will halt the forming of brain cells.
