I'm taking a class at school called "Theory of play". Basically, we discuss what play really is and the many theories about it.

I have to write a paper now. Of course, since I'm primal, I'm focusing my paper on what hunter gatherers/Grok can teach us about the importance of play.

I have most of my outline set up, but wanted to know if anyone here had ideas or sources they would recommend for me. Yes, I am using "The Primal Connection" as one of my sources.
