bad comparison...beauty is relative. those people always have that certain model look which is not always neccesarily good looking. its more of facial body/structure type deal. Plus with all the lighting and what not...trust me. if you ever met these people in person you'd be like wtf?
i know a few models and they barely resemble the person they are in shoots.
granted, alot of those people in those ads ARE good looking but its safe to say they represent a very very very small # of people. you'll only find people who like that in europe (european look is heavily favored in the modeling industry), and south beach, and maybe certain parts of NYC. Sorry LA....plastic surgery doesn't count.
i think we're also forgetting where you live plays a big factor in how attractive you are. if you're in a place with lots of attractive people your score will go down. When i lived up north i could say i was a 9...then i moved down here and its hard to hold your own in a place like south beach. dropped to a 7 lol
