My mom got me a new Fitbit for Christmas, and there is now a thing called a Sleep Score. I got a grade of 72 for a little under 6 hours of sleep last night.
I would like to be graded on a more punishing scale than this. Less bell curve, more bladed pendulum swinging from the ceiling.
Also, I read an article awhile ago that claimed 6 hours of sleep is just as bad as none. I forget what the logic was and what research it drew upon–it might have been mostly about cognitive function. But 6 hours of sleep is most certainly not as bad as none because the extent to which I feel like shit still matters.
