I don't know about the rest of the world but I'm gradually seeing my enthusiasm for pro football wane. A decade or more ago I would watch every play of every game on Sunday, particularly the Redskins. And I would be very much into the game, yelling at great plays, rapid heartbeat, etc.
But over time it's become easier for me to miss parts of games, or even the whole game. Yes, when I'm watching and the team is doing good, I really enjoy it. And I still read the Post articles and check the stats. But...
Why is it? 20 years ago or more, actually more, the Redskins were a good team. Since then they haven't been--don't think they've won a playoff game the few times they've actually made the playoffs. So there's that. There's also the consciousness of injuries, particularly concussions. And the game is slower, what with replays and challenges and more ads. Used to be a 1 o'clock game would end before 4, but no longer.
There's also age--my supply of interest seems to be shrinking generally. I no longer read every story in the newspaper, for example.
Age might be the determining factor.
