Humans are primates, duh

Anthropologists will tell you a hundred times over that female reproductive success is based on access to food and male reproductive success is dependent on access to females.

It took the hundredth time of me hearing this to realize how accurately it applies to humans. On a basic level, guys only want to score with girls, while girls are content eating chocolate...

Hence the birth of the classic dinner date. It satisfies both female and male instincts; males get to spend time with a female, and females get to stuff their faces.
