Summary: The United States is a graying country; the median age is near 40.

That is an approach advocated by Nick Allen, University of Oregon professor and director of UO's Center for Digital Mental Health . He and colleagues at the University of California-Berkeley recently made the case for expanded study of development and other issues for teenagers.
