I don't read fiction anymore except for one particular author. I used to (and lots of it when I was young!) but for some reason that I still haven't figured out why I stopped getting anything from fiction. I just did and I really don't miss any of it.
I do read non-fiction.
I have a few topics ongoing at a time that I explore. The topics might last for months or years until I eventually branch into something else, often semi-related. The books describing these real world things or explaining new views or ideas or angles are, to me, so endlessly fascinating that I find myself totally immersed in these subjects that I haven't even considered borrowing or buying fiction anytime soon.
I just sometimes wonder if I'm the only one like this.
