Researchers have found that women who live in matrilineal villages of the Mosuo tribe in southwest China, where grandmothers are the heads of the households, have lower blood pressure than those in very similar villages where men rule the roost. Women in these matriarchal communities also had far lower levels of inflammatory proteins in their blood, which have been linked to a host of chronic conditions, including heart disease and type 2 diabetes.
