Why do those Olsen twins Kate and Ashley always look so wore out and weak and sad?

these girls looked old and sad when they were babies, now they are playing the games of life but in a really screwed up world thats to hard for them. they are wealthy enough so that they can never ever feel safe from people wanting everything they have, and not being able to trust anyone will make you very sad.they have over indulged in everything(drinking,drugs,etc.) I am sure, which will make anyone look worn out. i truely feel sorry for them my self.
