How different are men and women?
Of all the things that are different between men and women, it's the weird biological differences that are arguably the most fascinating. Unlike social or psychological differences, which can be influenced by outside forces, male and female differences based only in biology (with a hat tip to evolution) highlight the traits that make male and female homo sapiens truly unique in the animal kingdom. We're a weird pack of hairless apes, it turns out. A look at the the objective, biological differences between male and female bodies reveals that men have larger brains, hearts, and feet, but have an inferior sense of smell, sight, and taste.
