17.
I have never understood why people call adults between 18 and 25 boys and girls or kids. I have never understood the term "college kid". If your in college, YOU ARE NOT A CHILD, YOU ARE AN ADULT. Even if you are in high school, but 18 years old, YOU ARE AN ADULT. That means I became an adult at the end of my junior year of high school.
Kid doesn't mean child. Just a relatively young person.
You want those to have the same age? Uh, not necessarily the best idea.
18 - that should be the age for everything.
Drinking
Driving
Smoking
Voting
Selective Service
I agree with drinking, but not driving.
18 year olds SHOULDN'T be allowed to drive? What about those that have to work and don't go to college?
