I know I have seen articles on this before. Did we discuss it here, maybe six months or a year ago?
More like ten years ago (or more).
I remember finding it interesting, because you would think that to be a schedule that would develop with technology. I mean, I get up around 0500, and this time of the year, it doesn't get light until after 0800 here. I don't know what I'd be doing for those three hours without electricity, good lighting and modern climate control.
I understand getting up for a little while in the middle of night to stoke the fire and do other things you might have to do pre-modern conveniences.
people would tend to ordinary tasks, such as adding wood to the fire, taking remedies, or going to urinate (often into the fire itself).
That last part must have been a little hard on the women.
