On Precautions During the Monthly Changes:
“The advantages of rest cannot be overestimated. A striking example of how it occurs to our mind. Most readers are aware how toilsome are the lives of the Indian women among our Western tribes, and also how singularly easy and almost painless is their child-bearing. The pangs of travail are almost unknown to them. The cause of this has puzzled even physicians. We can tell them. It is because it is an inviolable, a sacred rule among all those tribes, for the woman, when having her monthly sickness, to drop all work, absent herself from the lodge, and remain in perfect rest as long as the discharge continues.”
Years of toil + being nonwhite = nature’s own epidural. Scientific fact!
