“The adult male human brain typically weighs between 1,300 grams and 1,400 grams (2.87 to 3.08 pounds), making up roughly 2 percent of total body mass. Adult female brains weigh 100 to 150 grams (0.22 to 0.33 pounds) less than adult male brains. Brain weight varies by age, sex, and individual physiology. Men tend to have a slightly larger and heavier brain than women have, although this difference does not correlate with intelligence.”
I think that might be a typo in the women’s brains section. Less than 10% of what men’s brains weigh, but then later on they say men’s brains are “slightly” heavier? Something ain’t adding up. I think they forgot a digit.

Its probably to protect our brains from punching each other in the face so much throughout history.
Ive heard beards likely exist for a similar reason. Face padding…
In mine, it’s to be able to fit a little more headache in it.

Nope. Female brains are 10% less than men’s. That number isn’t the total. It’s the difference.
OOOOH I missed the “less,” thank you.
