I think this is an "abortion" topic....which simply means let everyone make their own decisions based on what's right for them and what they can live with.
There are many instances where I think it's "wrong" for people but there are also instances where I think it's ok and even a GOOD idea.
I think that if someone is altering their body strictly to "fit" in with what society sees as "perfect" that's crazy. But it's their money...let them decide (as long as they are fully AWARE of what their doing) IE not 12 years old (I just wrote a hub on this actually).
If someone suffers from an accident... IE a fire and is burned, a horrible car accident and loses a limb, the Miami incident of the canibal "eating" his face off....please by all means I think plastic surgery is warranted...I think plastic surgery orginated for these reasons.
Again though I think this is one of those topics where I could personally careless about what someone does with his or her body(ies) (assuming it's not my child, or someone "close" to me) they have the money to do it. Go for it!
Personally, I would not do it unless my individual circumstances "warranted" it. But then again I'm still semi-young I could revisit this topic in a few years and my opinion may change. But even then I want people to "but the heck outta my business"......
Just my 2 cents :)....
Good question (BTW).... that I of course wrote a "book" reposnse to.
