Yes. Because when you turn 18, age receptors in your brain turn on and cause your maturity gland to increase in size, meaning that you can now function as a normal person. Without the maturity gland, it is impossible to process information and to generate your own decisions. That's why you have to stay in school, or else you might die without someone telling you how to operate on a strict schedule. Ever wonder why dropouts don't usually make it? With their undeveloped maturity glands, they are highly prone to accidental death. Most of them just wander into traffic or forget how to eat. Good thing the government, and completely humanistic, nonprofit, medical industry helps keep those poor children in line. Don't forget chemo and radiation are highly successful cures with no immediate downside or risks for latent complications. [spoiler]My grandmother has osteoradionecrosis as a result of chemo and radiation from many years ago. It's generally a terminal illness, and there is a good chance she will bleed to death through her face sometime in the next few years. Many times, these treatments lead to other equally terrifying problems, and success rates are quite low. [/spoiler]
