Hi! I am an occupational therapist by trade in the US. I am also a 2 timer on this very stage. Your talk is great. It raises an important issue in many societies today. I am hoping my occupational therapy colleagues will take note and hope to present one day on this topic, too.
I really do like his view on the matter of child play, but the problem is that you as a parent are to blame when anything happens to your (or someone else's) child when they are (or should be) under your supervision.
Tell society to stuff it, make sure you know who their playing with, where abouts they are, parents phone numbers and that your state wont arrest you for it
