On this episode we are talking to Nicholas about his book, "BLUEPRINT: The Evolutionary Origins of a Good Society". In Blueprint, he introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide.  He brings some impactful questions related to grief to the table, like: Why do we have this capacity for grief? Why is it helpful for us as humans to have the experience of the emotions around grief?  "Emotions are a very primitive form of communication that far preceded our capacity for language - it's a more sophisticated type of communication."
