We're lucky that our bodies require sleep, otherwise our cultures would have us working 16-20 hour days.
(self.showerthoughts)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
This doesn't really make sense. Try it the other way: "It's a shame we don't sleep 23 hours a day, then we'd only have to work for a few minutes."
If we slept 23 hours a day I don't think we would have developed to the level of technology that we're now at.
We simply wouldn't have had enough time awake yet to achieve anything very much.
Eventually an asteroid would hit or Yellowstone would erupt and we would have probably only got to the medieval age, and then we go extinct.
