captain here. Every personal different when it comes to how much sleep they need. I can easily function off 6-8 hours but my twin brother struggles with less than 9. It's part genetic, part diet, and part rhythm. Some people only need 4 hours to function fully (like Margaret Thatcher), basically it's luck of the draw but a good diet and regular sleep cycle also contribute

used to reference Captain Obvious, which was used when someone points out the obvious. Now it's used when someone points out something that others may not know, which is kinda the opposite of the original usage.
