They say the general characteristics of faces that contribute to beauty include symmetry, i.e., facial features are mirrored across the vertical midline of the face. Apparently most of our faces are NOT the same in relation with the other side...
so heres a fun little game to illustrate that..
take a personal photo (it must be as straight on as possible).
next take it and cut it in half, then reverse the image and paste... see if you can recognize yourself in the mirror... then do the other side of your face...
I'll get the ball rolling....
