If I don't get food in my mouth, I'm still happy. If my pants are round my ankles, as long as I don't get arrested for indecent exposure, I'm happy. I'm worried about keeping my hair, not how it's combed.

'Why do you think it is...', I asked Dr. Cook ... 'that brain surgery, above all else-even rocket science-gets singled out as the most challenging of human feats, the one demanding the utmost of human intelligence?' [Dr. Cook answered,] 'No margin for error.'

I believe that the majority of times the scale tilts toward the good. It's this amazing thing that rolls on and if we get in the flow of it, that's God. And if we fight it, if we swim the other way, we're swimming away from the purest expression of this life.

It is ironic that in the same year we celebrate the 50th anniversary of the discovery of DNA, some would have us ban certain forms of DNA medical research. Restricting medical research has very real human consequences, measured in loss of life and tremendous suffering for patients and their families.

The laughs mean more to me than the adoration. If two girls walk up to me and one says 'you're cute', I'll say 'thank you', but I appreciate it much more when the other one says 'you make me laugh so much'.

The first part of my life was to be an actor and maybe have some success at that. Then [it was time] to find somebody to be in a relationship with and have a life that way. Because of Parkinson's, I had to change: How can I be of service here? Is there something unique to my situation that I can use to help people? I did not have the wherewithal to invent that. It just happened in front of me and had me join in.

If you asked my kids to describe me, they'd go through a whole list of words before even thinking about Parkinson's. And honestly, I don't think about it that much either. I talk about it because it's there, but it's not my totality.
