On March 28th, the movie “Screenagers” will be shown at Easthampton High School, presented by the Easthampton Healthy Youth Coalition. The filmmaker, who is a doctor and mother, documents the risks of the new technology that has most teens (and many adults) attached to their phones, constantly looking down, texting, snap-chatting and otherwise distracted. Carolee McGrath sat down with Jon Norman, the adjustment counselor at White Brook Elementary School, and Healthy Youth Coalition coordinator Ruth Ever.
