Well, it is an experimental procedure.
That's probably why they chose her....she seemed, well, maybe more "expendable" (I know that sounds harsh, but you know what I mean). In case they made a massive mistake, she probably wouldn't have to live very long with it.
"Yes, she does look fine, but I'm surprised the medical community deemed her worthy of a transplant. She attempted suicide, is a druggie, and chain smokes. Those are some immense red flags."
Well, maybe the surgeons saw this as a plus in that if things went wrong, people wouldn't be that upset that a druggie lost her life. However, from my point of view, this woman must have a life wish that is equal to any death wish she may have had earlier, as she has fought like heck to survive the dog attack and jumped at the chance for a new face. Perhaps being at death's door made her realize she really wants to live. One can hope.
