Until the book gets really good and you have to keep reading past your bedtime to learn what happens (or maybe that's just me)
But I can sometimes code until like 4AM. Weird.
I also find the idea of "forcing" yourself to read rather peculiar, but we're all different people. I wonder if there's genuinely something different in how the brain reacts.
I read the Zodiac book by Robert Graysmith in less than two days over break in college. Could not put it down.
