When I am dead, I hope it is said;

Your experience of waking up in the middle of the night and then getting a second sleep is the experience of two-phase sleeping that most of mankind used to experience before the invention of modern lighting. People living in the Amazon and other remote areas of the globe still do. Sleeping continuously is a actually abnormal for human beings. People used to talk to each other and interpret their dreams, sew, have sex etc. in the darkness when they woke up in between. They say that people are meditating trying to recapture this state of mind. Exposure to light late at night raises one's risk of cancer too since it affects pituitary hormone release.

I've been trying to beat back the light that our bedroom gets from the security lights at the new place with blankets and now shades over the windows. We might go to blackout curtains if that doesn't work.
