Yea, It is one of the strange factors playing with our sleep schedule, without our permission. No, I haven't read about that...only about animals though, who can make do with as little as few cumulative minutes of sleep.

I have met people who consistently only get four or five hours a night. That would kill me quickly, but some people seem to be able to do it.

This has been my routine for about 5 years now. You should try it sometime @flyyingkiwi 😁.
Thanks for reading, mate.
