Thanks for the video! I find this submission and the video you linked talking about being in an "open" or "closed" state ironic for me, because I just made a relevant comment on the football thread yesterday [1].
My argument was that rather than focusing so much on the reasons why people are or aren't interested in football, we should be concerned about the amount of time that debate and following football itself consume and how it is hardly beneficial to our long term growth. Having fun is important and people should spend time doing whatever makes them happy, but it would be better if we weren't so consumed by these pass-times and allowed ourselves to be disciplined. At the same time though we shouldn't completely shut everything else out. I used the term "open minded", and my intention behind the use of that term really vibes with the "open" state that Cleese talks about.
