In this episode of N of Us, I propose Broken Windows is the icing on our psychological bun, that there's something deeper in our psyche that turns us off the places where we are.

Barack Obama is arguably the most powerful man in the world. But is his power justified? In this episode of N of Us, we find out by wandering through the Italian Renaissance, taking savasana, grabbing a donut and buying the world a Coke.
