Why do you think you need to sleep at night?
You may be nocturnal.
I don't naturally sleep until at least 4:00 AM. Then, left to my own wild devices, I will wake in the early afternoon. They say about 1 in 100 people are nocturnal. We are needed. Throughout history as guardsmen and night-fire keepers, we have stood watch over the day-walkers. Much like the section of ADHD people have been essential for hunting and busting spies from other tribes, the nocturns have been maintained as a slice of humanity to help the whole. It is only recently that our niche has been eliminated and we have been forced to try living an unnatural daywalker schedule. If you think you may be a nocturn, you must stand strong. Work a night shift and find out how much better life is when you sleep when you were born to sleep.
