Good question, Mag
Since I got my CI last spring, I have felt somewhat " artifical ", I can tell that my body is uncomfortable with an object inserted into the side of my head. My body has tried hard to reject it many times - thus sending me to hospital a few times. I think that my body will never get adjusted to an foreign object in my body. Even my hearing is artifical - all I hear is mechancial sounds.
This is a lot to ponder on but excellent question to ponder on!
What about these with breast implants, chin lifts, etc?
