He notes that the term "teenager" is a modern construct that has no biological basis. What it does is justify treating teens who have adult bodies as kids, restricting their choices and contributing to 20 and 30-somethings not being able to cope in regards to traditional roles and responsibilities such as marriage and childrearing. He blames corporate America and schools; the former for capitalizing on the anxiety and depression that follows and the latter for setting up arbitrary rules.

The interview is worth the time spent.
