Science doesn't play that big of a part in age limits and although it should at the end of the day brains will mature at different rates and reach full maturity at different ages but at 18 the brain, the majority of people have reached a certain maturity " In his office at the NIH, Giedd points to an image of the brain on his computer screen that illustrates brain development from childhood to adulthood. As he sets the time lapse in motion, the brain turns blue rapidly in some areas and more slowly in others. One area that's slow to turn blue- which represents development over time-is the right side just right over the temple. It's the pot in the head where a parent might tap a frustrated finger while asking his teen, "What were you thinking?" This underdeveloped area is called the dorsal lateral prefrontal cortex. The underdeveloped blue on Giedd's screen is where the thoughts of long-term consequences spring to conciseness. And in teen after teen, the research team found, it's not fully mature." (Davis, 252) At 16 a teenager is not able to process the consequences that are presented in certain situations but at 18 the brain is much more mature in very little time, the difference between 16 and 18 is very drastic. I believe that teens should be allowed to drive at 16 but there should be a longer process to assure that the teens are aware of the consequences that can come with driving, I also believe that people should be allowed to drink and smoke at 18 since legally they are already considered adults and deserve the rights that come with that title.
