The debate over whether models are good or bad is irrelevant. The fact is that they exist, the body image they portray exists because it sells and it is on some level a manifestation of socities aspirations, aspirations towards perfection. If that body image did not sell, if that body image did not work for the designers then they wouldn't use it.
Diagreeable, irrational things happen in the world all the time and it's because people don't think, most of people will go through their lives like a pack of headless chickens flocking together, actually caring about the mindless crap we see in magazines and portrayed through the media.
Most people don't ever take a chance to reflect upon themselves, build confidence through getting out of their comfort zones and educate their minds so that they will be able to form their own opinions on what is going on around them in the world and why.
Everyone has a certain level of energy and time to devote to activities as they choose. It is ironic in that many models with travel the globe, strutting the catwalks yet fail to educate themselves in the worldy way that would enable them to see the horrible deal they are getting from a rational perspective; a strictly controlled diet, hours of exercise, mindless wearing of often ugly, eccentric clothes only to be shafted to the outskirts of society with their dieing youth once the next generations of underagers come through-this outcome is inevitable!! For anyone who believes that you can win in this game is destined to lose from day one, unfortunatley in the true nature of human beings, most peeople will become victims of such cycles and never seek to build the confidence to be able to look at what is happening, the images out there and know that they are wrong.
I am only 19 years old, I have lived a jetset lifestyle and I take an autodidactic approach to my education and I would say after a hard day of striving for a high distinction in a uni assignment I love to go and buy a crappy celebrity magazine or browse through a vogue just to tilt the IQ scale a little in the opposite direction for a few minutes

I also love looking great, doing sport and making the most of my youthful appearance whilst not having to wear makeup! I like feeling pretty to. I had the oppurtunity to be a model, I am the naturally skinny type, but even the naturally skinny type still need a level of vanity beyond healthy standards that I was not willing to give based on this decision; that striving to get rid of tiny, meaningless imperfections only appearing to be important in the eyes of popular culture is simply absurd - birds of a feather flock together, the average person in society is an idiot - if you used your brain who would sacrifice the optimal lifestyle combining pleasure, health and fullfilment to adapt to an image designed by a pack of irrational fools?
I look at some of these models and I pity them for not having the wisdom they may gain later on in life (if they get there!), they are pawns destined to loose in society's game of expectations and few will probably ever discover that insight whilst they are too busy worrying about a stretch mark or two - but at what cost!!!
Anyway I say to any girls out their aspiring to be models, don't waste your youth, sure strive to look your best and gain a healthy body, you can look as good as a supermodel if you look after yourself and embrace your natural body shape, wear the right clothes and use the right products but educate yourself, live, live live!! There is a whole world out there and nothing is stopping you from doing anything except yourself, don't waste this time of your life and try to have empathy with yourself in ten or twenty years time...think about it.
