I read a lot of books—an average of 135 per year. And yes, I remember them—most of them, anyway. And every once in a while, a book grabs ahold of my leg and won’t let go. That was the case with “The Power of Strangers: The Benefits of Connecting in a Suspicious World,” by Joe Keohane. In fact, it affected me so strongly that I closed the back cover, went to my computer, found Joe online, and called him. He agreed to be on the program, and this is my interview with him. You’re going to want to hear this one—and you’re going to want to read the book.
