It's amazing how much our world has changed, with all the technology, social factors, and general cultural shift that we have experienced. Even our sleeping lives have changed. In the Pre-Industrial days sleep was broken into two parts with a hour or two of wakefulness separating them. During this time people would perform lots of tasks, and visit with others. It was kind of like their social hour, people were busing during the day working to make a living so they made time for social interactions in the middle of the night. Smart. The people did however still attain the eight hours of sleep needed, they simply would go to bed earlier around nine or ten. A Danish pastor once quoted "Stay til nine you are my friend/ Til ten, that is alright/ but if you stay til 11 you are my enemy" the people in this time period went to bed much earlier than we do now days when the night is usually full of our social interactions. The peculiar way that society has been evolving from having a couple hours in the middle of the night to wake, to staying up later.
