I can read 200+ books a year if they are relatively thin (say sci-fi books like The Gates of Creation or a thin non-fiction book like Eva Illouz's Cold Intimacies)

I had a point maybe 10 years ago when it seemed the influx of information from reading at my maximum rate was making me anxious and disturbing my sleep and I deliberately got into playing video games like Advance Wars and Fire Emblem that recombine a small number of elements endlessly.

I've been losing my interest in video games and for me reading has been transitional to my next act. I find now I can read a lot if I avoid reading things that affect my emotional equilibrium. Today I have to really watch out for anything that makes me feel envious of other people.
