I definitely put a vote down for testosterone.

Until the age of women's lib, there used to be a thing called chivalry. Lifeboats would load "women and children first" then the older men and so on.
It is true that many cultures allowed the men to eat first, there is a good reason for that. The majority of heavy work is done by the male because of our sexual dimorphism. We require larger caloric intakes to compensate for our musculature as well as our increased activity out of doors. Much of womens work revolved around the hearth and homestead, places sheltered and warmer than the unforgiving wilds. It was mostly repetitious and monotonous, but rarely life-threatening to the extent that plowing, hunting, fishing, and fighting off intruders and raiders would be.
