“After thirty years of intensive research, we can now answer many of the questions posed earlier. The recycle rate of a human being is around sixteen hours. After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours. Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping. Finally, the human mind cannot accurately sense how sleep-deprived it is when sleep-deprived.”

Jesus christ
Sleep is a super power
That last bit makes a whole lot of sense and it honestly astounds me, that I never once considered it.
But yeah that seems very obvious.
Finally, the human mind cannot accurately sense how sleep-deprived it is when sleep-deprived.
This explains why i am literally unconscious for the entire weekend. When the lockdown first happened I slept a full three days.
