It Takes Longer for Each New Generation to Finish School, Get a Job, Marry, and Have Children

According to Laurence Steinberg in the New York Times, each new generation takes longer to finish school, get a job, marry and have children. It turns out that this isn't such a bad thing, as it may allow the brain to maintain its state of "plasticity."

Studies reveal adolescence to be a period of heightened “plasticity” during which the brain is highly influenced by experience. As a result, adolescence is both a time of opportunity and vulnerability, a time when much is learned, especially about the social world, but when exposure to stressful events can be particularly devastating. As we leave adolescence, a series of neurochemical changes make the brain increasingly less plastic and less sensitive to environmental influences. Once we reach adulthood, existing brain circuits can be tweaked, but they can’t be overhauled.
