Everyone loves a baby face!

"The results of this experiment show clearly that childlike characteristics (large, round eyes, a large curved forehead as well as small short nose and chin) can enhance attractiveness. Only very few (9,5%) test subjects rated mature "original women" as being most attractive. Most of the preferred female faces contained childlike proportions of 10 - 50% (for details see report!). This means that even the most attractive women become even more beautiful, if facial proportions are made more childlike."
