You might just be chronically tired or worn down from the stresses of life. It’s pretty common.

Another thing is as we get older a lot of people will choose more “challenging” adult books and then just be totally bored lol. I read young adult and kids books sometimes (how can I give a book to a child if I haven’t read it myself?) and it’s always surprising to me how they can be ripped through in no time at all.

But in general I think you’re probably right that literacy can decrease with disuse. It seems like most things about the mind and body trend that way

Oh, your link is broken in the post itself I think
