Jeez. Parkinson's, huh? That would explain it. For someone as bright and animated as he was, I can see how increased risk of dementia and loss of motor skills would be a blow.
I'm personally in favor of voluntary euthanasia in cases of terminal or massively debilitating illness/injury, but while I sympathize with Williams's choice, I can't say I like it. Treatments for Parkinson's are imperfect but effective, and while the dementia aspect personally scares the shit out of me, it's not a sure thing. Look at Michael J. Fox- he's been battling Parkinson's for over twenty years now, and yeah, it's had a significant impact on him, but he still leads a happy and functional life.
Wish he'd thought this through, decided to battle it out. It's hard, but he's faced hard times before. I'm sure he could have beat this. Gonna miss him.
Started off with World's Greatest Dad when the news broke. Watched The Birdcage yesterday. Tonight? Toss-up between Hook and Moscow on the Hudson.
