I used to read a lot, almost constantly as a child, but as I got busier, I slowed down somewhat. My quiet reading time became 2 - 3:30 a.m. because I am a terrible sleeper, but since I started taking an over-the-counter sleeping pill, I've lost my reading time.
I have little patience with fiction, unless it is outstanding, because my reading time is so limited, I might as well learn something while I'm at it. My library seems to consist of biographies of kings, queens, founding fathers and adventurers, and shipwrecks.
