In your book, you mentioned that in passing to some extent, but it's more than just in passing. We raise children in a way that's in the West that's very different from our evolutionary heritage. You take a baby to Penzi and put it in a cage by itself without its mother and it will go crazy pretty quickly. What I tell people is: Act with your children at home as you would if you were camping in the wilderness. The bigger the group you're with, the safer you are.
