I like how pointless the posts got after Stuntman did detective work.
The face is also used in psychology because it meshes general shapes of each part of a normal human face to make the most generic person in which case you'll notice one of more features that resemble someone/something you've seen recently. (Forehead, Jaw, Cheekbone, Lips, Nose, Eyes, Eyebrow Hair/Bone, Hair, and Ears)
One example of a face was used in class for me last semester, although it was of a woman.
