How Disgust made us Human

[Luxman]

"When we’re worried about disease, it appears, we’re drawn not just to Mama’s cooking but also to her beliefs about the proper way to conduct ourselves – especially in the social arena.

Now’s not the time to be embracing a new, untested philosophy of life, whispers a voice in the back of your mind."
