Nowadays, I pace back and forth in my room with the lights on. It's good exercise, and I can get engrossed and read for a long time.

As a child, I used to love reading in bed, but as a teen, I read that was bad because it conditioned you to stay up late (maybe that's why I always had trouble sleeping as a kid...), so I stopped, but if I didn't work and didn't need to wake at any specific time, I'd totally be doing that too.

Lastly, I used to like reading on a couch when I was younger, but nowadays, I'll read anywhere that has a seat in the cases where I'm not walking.
