People say symmetry in a face is beauty?

As the other person said, both sides of the face are exactly the same. As an example, the distance from the outer edge of the eyelid to the nostril will be the same from either eye or the distance from the eyelid crease to the brow will be the same distance from either eye. I saw a show about this years ago. During the test the testers put two pictures on the screen (one face symetrical and the other not symetrical). Babies would stare at the symetrical face which would imply beauty. But look at Heidi Clum (Victoria Secret Model), her eyes are different (one sags) so her face is NOT symetrical but she is still pretty.
