what is normal?

so, what exactly is "normal"? i honestly don't have an answer to this question, but intend on writing my second essay about this question specifically due to body image.  it amazes me how easily the media can have such a pull on the american public, impacting the way people (especially women) view themselves every day.  televisions shows place people into such a funk about the way that they look and are viewed by others, thinking that its a huge deal to be such a small size when it comes to clothes because this is one of the pressures that the media places on us.
