I had a discussion about this in class a while ago. It was pretty thought provoking and I'm still thinking about it. It was about what life would be like without a mirror or light reflection to show us what we look like. The question was brought up, Would you be the same person you are now if you never knew what you looked like? How would everyone act if they only knew what each other looked like and not themselves? You could look like anybody for all you know, so how do you know if you look different than the people you see?. You don't..it would be a mystery and also give the illusion that we are all the same looking. Yet in reality we aren't the same looking.
