My age makes me think how valuable life is. How bad is something like Parkinson's in relation to not having life at all?

Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.

So what I say about Tracy is this: Tracy's big challenge is not having a Parkinson's patient for a husband. It's having me for a husband. I happen to be a Parkinson's patient.

I often say now I don't have any choice whether or not I have Parkinson's, but surrounding that non-choice is a million other choices that I can make.

If one of my kids reads a book for school and I can have a conversation with her about the book and I sense that she gets what the book is about, then it doesn't really matter to me if she gets an A on the paper.

I urge you to be challenged and inspired by what you do not know.

No, I got a GED in my 30s. My kids know that I never stop learning, and they know I love reading. I have books overflowing everywhere. I am current on today's events and I read the paper every day, and we talk about it, so they see that appetite.
