David Letterman is retiring. Such great memories of watching him over the past thirty-two years!
Playworks is a super awesome group. They are used on many playgrounds in Boston and it has helped with disruptions and fights on the playground. I've read that teachers have reported a better learning environment too as the ALL the kids are active and come back ready to focus.
I would support this type of program for schools over self defense lessons.
That program does sound awesome!
