If you're old enough to die for your country, then you're old enough to vote, drink alcohol, smoke cigarettes, have sex with a consenting adult preferably of the same species.

What I find ironic is that you are required to pass a driving test to drive a car, but as long as you're at least 18 and have a pulse you can vote.

Give children, and those who think like them, the right to vote and they'll choose double portions of cake, candy, and ice cream for every meal.
