Times change.   Medical understandings lead to social and cultural changes.   This is one of them.   In some parts of the world women are still required to leave the home and stay in an outbuilding or even just outside.  I remember about a year ago a woman died because her period happened during a hurricane and she was forced to go outside and stay there during the storm.  It was in a country that had religious laws instead of science as their fundamental rule making requirements.   But she was a woman so only her family that loved her really cared about it.    Are we ready for the US Christian Taliban take over now?   Hugs
