It's all bedtime reading honestly. I got a new kindle at Christmas to finally replace my first gen one, and now with the backlight I can read in bed without waking the wife. So I go to bed an hour earlier than I used to, and instead of browsing my phone for an hour, I read for an hour... or three.
The whole point was to fall asleep faster than staring at a screen, but I keep picking page-turning books so it's counter-productive
