I came upon a lecture that discussed how people think the same thoughts perpetually. All day, all week, maybe in different orders but still the same thoughts, whole lifetimes like that. About themselves, about their co-workers, about their children, parents or partners, over and over and over. Used to think that snippets of songs that get stuck in one’s head could be understood as being melodically infectious but then again many of those tunes are also unappealing. I’m not interested in hearing Baby Shark again, poof – and there it goes again. How does my disinterest explain it’s staying power? Unless it has nothing to do with you or put another way unless the very design of our minds doesn’t include choosing what you will think next, like the flow a river just constantly supplied.
