No matter how much fame you have, it's not something that belongs to you. If I'm famous, that doesn't belong to me-that belongs to you. If you can't remember who I am, I'm no longer famous.

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.

I truly believe that we have infinite levels of power that we don't even know are available to us.

That's the way I look at things - if you focus on the worst case scenario and it happens, you've lived it twice. It sounds like Pollyanna-ish tripe but I'm telling you - it works for me.

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.

Since I'm not sure of the address to which to send my gratitude, I put it out there in everything I do.

I might have skipped class, but I didn't miss any lessons.
