You would be suprised how much you are influenced by society even without knowing it.

Some people are more succeptable (I don't think I even came close to spelling that right,) to it than others, of course, but it's pretty damn hard to not be influenced by society in any way, because most of the time you don't even know it's happening.

For instance, most women are constantly looking for what "normal" is for their bodies. When the majority of people are fat, normal starts shifting in that direction, and it becomes more acceptable to be fat in society.

I've always said it needs to stop being acceptable. In this day and age we're told that the fat kid is just like everyone else, but he's not, he's a fatass and we're told that's alright so nothing gets done about it.
