Two sexes have significant difference between their
prakruti and physical pratikruti. (nature and appearance)While a woman can be compared to
silk cloth, man to jute cloth. Woman is "prakruti" according to
Indian philosophy. The differences in the body chemistry and minds
are two poles apart. According to Indian customs, cremation requires
burning the body. The last to resist burning to ashes are pelvic
bones in case of women, while similar bones in men are shoulder
bones. Hence the name "prakruti" or "kshetra" for women,
while "Purush" for men, meaning warrior principle, accomplishment-
achievement ambition in men. Many psychiatrists and students of
various branches of social sciences have struggled throughout their
lifetimes to study these differences.

Author has seen many women aged more than 90 and having very silky skin and hair. They had more than ten children and large hips. This means that they have good fertility too. The Vatsayana, (the equivalent of Masters and Johnson in west), who wrote Kamasutra, the oldest treatise on sex and man/woman relationship, describes woman with large hips as "hastini", the one who looks like an elephant. Do you know the life of elephant?

Vatsaayana says that the hastini woman easy to satisfy in sex, bears more children, her deliveries are easy and is very much attached to children, She has generally large breasts too and feeds every baby well. In short she is destined to be a good mother!

So Dr Lauren Lissner, you have reinvented wheel. Indians have exhausted almost every subject in which west is interested.
