 This is The Middle. I'm Jeremy Hobson. This hour, we're asking you, are you addicted to your phone? And if so, what are you doing about it? You can call us at 844-4MIDDLE. That's 844-464-3353. I'm joined by Dr. Anna Lemke, professor of psychiatry and addiction at Stanford and author of Dopamine Nation, and Johan Hari, author of the book Stolen Focus.
