Dr Peter Gray has been saying it for years; kids are suffering from more anxiety and depression in part because we've taken play away from kids and replaced it with structured or online activities and school work. Dr Gray is a professor of psychology at Boston College and a world authority on the importance of play. He shares his latest research that shows kids who aren't allowed to play freely lose their sense of autonomy, have trouble thinking independently and lack of play can even impact their ability to work through problems with other kids. He shares his research that shows that play makes us more human.
