I was reading up on sea sponges, as the sponge thread intrigued me.
Since finding out about periods, then experiencing the discomfort and hassle, I'd never thought there was a real reason for them, or anything positive to be said. So I was suprised to read this -
There is in fact a purpose behind the body regularly shedding the uterine lining and letting the blood flow away — the uterus is cleansed of any unhealthy micro-organisms that might have gained entrance and taken up residence during the preceding cycle. By ridding the uterus of cells that might have become infected, the immunological integrity of the body is protected, the incidence of sexually transmitted diseases is reduced, and the uterus is kept clean.
I wonder if my DDs will view menstruation differently when I've told them about this.
I wonder as well - if periods weren't such a taboo, would they be the hassle that they are now?
