Twenty five years ago Robert Putnam noticed something odd. More people were bowling, but fewer people were bowling in group leagues. But, why?  The answer has to do with a gigantic sociological shift towards aloneness. And that was before the pandemic, work from home, videoconferencing, the iPhone and the Peloton. It's crazy how far ahead of his time he was. And now 25 years later he's looking like a modern-day Nostradamus.
