I just listened to her being interviewed yesterday and I think she said one of her grandparents had Parkinson's. It's the first time I ever heard of there being a family connection.
I just saw an internet video of her: It seems she lost the good looks she had when she was young (most people do of course) and now her voice. That's so sad!
She said she just published a memoir.
