Well, I'm aware, but just before seeing this thread I was addressing a similar issue with a thread posted by an author who waxed loquacious on the state of the brain of a 25 year old (Dean Burnett) who clearly didn't know what the military counts on in terms of the state of youthful brains.

Think about it--there's a reason why the voting age was lowered from 21 to 18 but never to be considered was raising the military draft age from 18 to 21.
