Consequences of our improved health?
This reminded me of something a med school professor pointed out in my hematology class. In the early sixties, hematologists became cognizant of the significance of iron deficiency anemia in premenopausal women. Countless women suffered the fatigue and malaise associated with the low blood count that often arises from their menses.
When this situation became well-recognized by physicians in that era, it was easily rectified by daily iron supplements. This rapidly built up these women's iron stores and "cured" their anemia and its symptoms.
My professor's "moment of clarity" came when he realized that this discovery occurred at the same time as the rise of feminism in America. He postulated that prior to that, the unfair inequality women suffered at the hands of men was upsetting but they were just too tired to do anything about it.
