I guess it is human nature that we put so much value in what the opinion of others are of our looks.
It definitely is human nature. We are built to be judgemental in many, many ways and for reasons. It isn't just fashion.
I am more concerned what my opinion is of my appearance than others now.
I think I am the same. Perhaps it is again natural, as we see ourselves degrade with age, with not a lot of good going forward :)
Want a face that looks like a scrap yard, have at it. Its you.
But don't expect to get a job at the reception of a law firm too :D
