Why God Made Teenagers.....

I have come to the conclusion that teenagers are very important to God's design of the world - they are His fail-safe to insure that humans do not over-populate the world. They are little agents of natural selection. Why else would cute and sweet little children morph into vitriolic despots of stupidity? Why else would their frontal lobe go into hibernation the day they turn thirteen and not awaken until they reach their twenty's? Obviously, it is so that humans will not overrun the earth, so that their population will be kept in control by the stupidity and annoyance of teens. They either do things so dumb that they reduce their own numbers naturally, or annoy adults to the point that their numbers are reduced in other ways.
Why else would God create such......creatures?
