What time do you go to bed? What time do you usually get up? How much time do you have for sleeping?
I heard that some people (like Elon Musk) sleep for 4 hours in order to have more time to do things during the day. Is it dangerous to health?
depend on what time my daily Job/obligation was done .
it sometimes 9pm? 11pm? sometimes up to 3am if there are something need to rush.
But i make sure of having a 5-6 hours sleeping time because that is needed for my Health and Mind settings.
