Hey Andreas. Your question came in after I’d already recorded the last video (a few days before posting). Anyway, many societies have “menstruation huts” a little apart from the village where menstruating women can be off on their own a bit. Some anthropologists think this shows signs of fear of women’s blood. Others think the women enjoy a break from dealing with kids and see it more as a benefit to them. No tampons, but certainly most groups cover the genitals with leaves or some kind of woven cloth, so the bleeding would be obscured.
