I think that the age limit in the US is bull. By prohibiting it, teens want to do it. Same thing with smoking.
European countries fair perfectly fine without age limits on drinking. What makes US politicians believe that we're incapable of handling alcohol? Of course, there will always be someone who gets killed due to doing something stupid and alcohol related. But I don't believe that those people should call for laws. It'll still happen with the laws in place.
Ridiculous, I say.
EDIT- I don't smoke!
