TO THX:
Medically fine, but losing the will to live? I call that depression and the person is not medically fine in the head in the case of their brain chemicals. That couldve been the reason for her death, since the scene between her and Anakin when she got choked "showed" how much she was "really disappointed" about her husband joining the dark side.

I have never seen anybody look that good and be severly depressed, then just die all the sudden. Heh, mabe someone should put a depression in Lucas's head. Anyway, all joking aside, I will have to see it again to catch what I missed.
