So I'll answer the second part. Whenever I massively oversleep, I feel lethargic and broken. So no, 8ish hours a night is what I prefer.
Me too, If I could get that! But I can't, I get 3-5 hours a night so I sleep 1-2 hours in the afternoon too, to make up for it and have a lucidity renewal 2 times day! But in the saturdays I sleep 10-12 hours, the only day in which I can afford to feel completely rested for quite some hours after waking up having loads amounts of energy. If you have problems keeping good score with yourself doesn't mean everyone else is. We are all different, all I meant is do what feels right for your body, for your mind, not for everyone else as a concept of so called high or higher society.
