This past weekend at Dad's, I could not sleep! I began to ponder this question. What do you think would be the major differences if we did not require sleep?
I think a huge difference would be that there would be two categories of people...those that do their job at night and those during day. Granted, there are jobs like that now, but there would be so many more, if it was not "normal" to sleep at night. So, we would probably befriend more people who kept our schedule and forming bonds and anything social would be defined by meeting people who kept the same schedule.
