Absence of a "face."

 Sometimes, when I look at people’s faces, instead of perceiving a face, I see an organism composed of eyebrows, eyes, nose, and mouth—each existing solely for function. Eyebrows prevent sweat from reaching the eyes. The eyes are two flesh spheres through which the organism perceives the outside world. The nose enables breathing. The mouth serves nourishment. And so on. If seen through such a purely biological lens, no “face” ever forms.
