Ever wanted more. After all, women weren’t equal to men. They were better. Certainly not in strength or their skill in killing things, but when it came to propagation women absolutely trounced men. Men could bring some chips to the party, but that shindig was always going down in the belly of a woman. And considering that the hardest part of gathering food now was finding a parking spot, strength and killing things were significantly less high on the list of key survival traits.
