I guess it is human nature that we put so much value in what the opinion of others are of our looks. Not sure if that ever changes or if it is supposed to with age, but I find I care less no that I am older what others think. I am more concerned what my opinion is of my appearance than others now. Not sure if that is correct behavior, acceptable or what, but it is a fact.
As far as others and what they look like, I guess there is still omemjudgement, but for the most part I could care less anymore. Want pink hair, go for it. Want a face that looks like a scrap yard, have at it. Its you.
It definitely is human nature. We are built to be judgemental in many, many ways and for reasons. It isn't just fashion.
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 :)
But don't expect to get a job at the reception of a law firm too :D
