My son starts Kindergarten tomorrow, so perfect timing for this article! While he's certainly not an aggressive kid, he has a typical 5 year old boys imagination...the world revolves around sports, super heroes and fighting bad guys. Definitely an interesting read, but I think the info below really summarizes the benefit/risk scenario for our boys play time.
I really think a lot of our problems as a society can be boiled down to the educational disenfranchisement of boys. There is a palpable, simmering, frustration in a lot of young males. And it is only going to get worse until the issues of educational reform are addressed.
