Explain Like I'm 5 (ELI5)
Objective and layman-
ELI5: How does bowing work in Japanese culture. I’ve heard there are so many subtleties to bowing that a Westerner should never attempt it. Is this true? What are some of these subtleties?
ELI5: Why are chickens more likely to be contaminated with salmonella and not other animals
ELI5: Why do you sometimes wake up more tired with more sleep, and more energetic with less sleep?
Quite often I am more alert and can concentrate better with 5 hours of sleep compared to sleeping extra with 9-10 hours of sleep. Is there a biological reason behind why oversleeping can cause you to be more tired?
