You're in the Army? Have a beer.

The one thing in this country that drives me crazy it the drinking age. i think it is SO STUPID and ridiculous that to join the military and put your life on the line you have to be 18, younger with parental consent, but you can't have a beer until you're 21. People say it is because kids cannot handle the responsibilities, but they can handle the choice to go overseas to war. No. It's idiotic. Every other country in the whole, wide world has a lower drinking age. Do you hear stories about all the drunkies messing shit up over there? No, no you don't. If America would be more tolerate of drinking, kids wouldn't go out and do it to rebel. Half the kids who drink underage are only doing it because they can't. If the drinking age was changed, that would no longer be an issue. So, all in all, if you can go sign your life over to the military, you should be able to celebrate with a drink.
Legally.
