It’s all about symmetry.
Although you probably learned all about it in art class or geometry, men’s biology seems to be fixated on symmetry. Symmetry is the idea that"when divided in half"each side of an object, person, or image mirrors the other.
Of course, men aren’t simply attracted to any symmetry they see. (Unless they’re one of those 19th-century male nature writers who was aroused by plants.) We are all specifically wired to look for this characteristic in other human beings and use it as a subconscious tool for rating attractiveness, according to the journal Symmetry. There are a few different theories about why this is the case. Some researchers think symmetry is believed to be an indication of overall health.
