This is a great episode of Ideas which takes highlights from Footprints, a symposium on Sport & Society. The first two speakers speak about how activity can help children with autism. The first speaker is a psychologist who talks about an innovative classroom setup in Eastern Canada. The second speaker is a young woman with Aspbergers (on the Autism spectrum), a novelist, who recounts how activity helped and still helps her cope in her day to day life.
