Cosmetic Surgery vs. Body Modification

I would define cosmetic surgery as a decision someone makes to change something about themselves because they feel it must be done. Either they feel that something is inadequate in their own mind or standards or it is something that is impeding their everyday life. i would say that cosmetic surgery has different levels of intensity depending on how enthusiastic the person is on what they wish to change. Often times, it is a decision made by society and the standards that we have that make people want to change their looks. Body Modification I think is a little more intense because there is a more serious aspect in many cases. Body modification to me menas somehting more unnatural like lip rings, tattoos, or ear hoops. I feel body modification has a different meaning and purpose than cosmetic surgery because it is reconstuctive versu cosmetic changes. I think the overlying difference is the appearence of natural vs. something manmade.
