There are so many hobbies that are leagues more important and productive than knowing who won which game of what when. I’m sorry but I think even media / pop culture knowledge edges out sports. Your example alone; Moss is a cultural touchstone we can use to further quantify and share an understanding of the human experience. Creative writing is done by real people, and exploring the lives of fictional people or elements of fictional worlds is how we explore our own lives and world. It’s art and art is integral to humanity. I’m sure play is too and if you get enjoyment out of watching people play ball then more power to you! And I agree that not everything we do needs a purpose, but I don’t think that contradicts my initial comment. I think most would agree that some hobbies further you as a person, some further humanity, and some are mostly just a time and productivity sink.
