Dr. Eran Levin from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv Science may have figured out why women always feel colder than men. We might have evolved that way to encourage us to spend more time APART. Before we were civilized, it wasn’t always beneficial for male primates to stick around and help with the kids. The males would eat all the food, or be too aggressive. So even just hanging out in the shade, while females preferred sunny spots may have been a benefit.
