There's talks of lowering the legal drinking age to 18, and it's actually getting some traction.
Did you know, you only have to be 21 to drink in like half the states? In some states, if you have a parent or guardian present, you can drink below the age of 21. In some states, if you're married and your spouse is present, you can drink below the age of 21. And in a few states(California is one, if I remember right), you can drink below the age of 21.
