A weird thing I've noticed happening to me is my flagging ability to focus on intellectual topics. It's weird because I used to have immense interest in everything, as my handle indicates, but now I have no interest in anything. I was looking through unz.com's ebooks which were all on things I would have once-upon-a-time downloaded and read. I think it's because I increasingly feel like learning information for the sake of argument is pointless and so my brain is no longer curious about topics but actively rebels against them. I suppose now I'm the complete opposite to my handle. It's almost like a Flowers of Algernon situation except I'm not going retard.
I suspect some of it is due to overstimulation. I reduced my mental stimulation to mostly this site, but lately I've been getting into soccer and playing a co-op game with a friend, and now that I'm 40 I only have the energy for a few things. After 6pm I seem to be done, just incapable of sitting and enjoying a good book. This has never happened to me before, I used to be able to burn the midnight candle absorbing stuff. Has this happened to anyone else, where it's like you suddenly decide you're done trying to be intellectual and clear off your plate?
