Drinking age

This is one that i think most of yall can relate to. I believe that the drinking age should be eighteen. The United States is one of the only countries who insists on having the legal drinking age of twenty-one. But why? around 18 when kids are going to college and even before then they start drinking. Why not just make it legal if they are going to do it anyway. Also many teens drink just because it is illegal, cause its the bad and dangerous thing to do. With a lower drinking age maybe people would be less careless with alcohol. My parents have let me drink since i was fourteen. The fact that I was allowed to do it made me responsible with alcohol now that i am older never getting too drunk and making sure no one goes over their limit at parties.
