How different would the world be if humans did not require sleep?

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.

Well for one thing we'd get a hell of a lot more done every day (and night).

That would put an end to the old saying "there are not enough hours in the day"

There'd probably be about 58,491,723,942 people in the world by now.

^^ LOL - good point!

I think we'd get a lot more done, but I don't know if we'd be all that much more healthy, as down time is good and allows us to rest and relax. I think some people would get so caught up that they'd work and work and never take a break, which isn't healthy. Others would be the opposite.

I agree that that the world would be more overpopulated, but at the same time I also think we'd die sooner.
