Somewhere on here..or i think it was here awhile ago i posted about a study done on some of the last natives in americas and they got them to put the watch thingys tracking on and they studied their sleep pattern and found they sleep in two shifts and only for a short period were all 25 of them asleep. I cant find that article to post but this video popped up today talking about that and how its recorded in our history all humans use to do that or at least large portion of population done.
