Let's Face It, Transplants or Cosmetic Surgeries

Ther is a Mr. know-it -all in "WIRED", who is able to give help when you are nevigating life in the 21st century. IN the recent issue (October 2006), Mr. Know-it-all tells a lady that she need to confess to her fiance about her cosmatic surgeries if they want to add kids in their future marriage and also, it is about the genetic honesty.
How many people are involved to cosmetic surgeries or tranplantation?, since they are so common and affordable to many of us? The biotech is a real miracle. Do you still remember Isabelle Dinoire, who got a transplanted face few months ago? (http://www.kydepot.com/isabelle/) People debated, mostly around the culturual issues. Has the medicine gone too far? Is that face her face or the donator's face?
If I was in the same situation, i mean, If got somebody else's face, will I be able to face myself? I try to convince myself, a transplanted face is just like an transplanted organ but that is only in the theory of bio-tech. As a peoson, a face could be the primary organ of his/her personality.
But how about the cosmatic surgeries? A changed face is still her/his face? I guess most of us would say yes. I don't think we can look at a person and not see her/his face as her/his face. For example. we are easy to forget a person's old hair style when he has a new hair cut. But it is hard to people to accept Isabelle Dinoire's new face but easy to accept the changes after the cosmatic surgeries?
