beauty is in the eye of the beholder.

for tongue there is sweetness for nose there are nice fragrance for ears, there are wonderful sounds (music) for skin, there are comfortable touches like that, for eyes there is beauty stimuli can be of two types 1- those giving pleasure, happiness, comfort or good state of mind 2- those giving sadness,disgust,trouble, or bad state of mind if something or some one stimulates us in a way that brings good state of mind, we call it admirable, attractive,charming, approved, fair, favorable, popular, nice,lovely,etc so beauty is a stimulus, that gives comfort or happiness that's why people (we) like it , ie, popular

It is a basic human instinct to respond better to people who look attractive. Even in courts good looking people are more likely to be acquitted. So be good looking and you will get the best out of life))

I don't know why i'm so popular :P

sex sells, bro ;)
