I think the scariest person in the world is the person with no sense of humor.

In fact, Parkinson's has made me a better person. A better husband, father and overall human being.

I have a remarkably normal life.

Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all.

I can say, "I don't have anything I regret!" But I can also say, "I can go forward in my life the way it is and I don't think I'll accrue any future regrets."

My view of life is colored by humor and looking at the best in any situation.

When I started it [non for profit], I thought, I'm not smart enough to do this. I had no experience in management, no experience in administration, no experience in nonprofit; but then this phrase came into my head: I only have to be smart enough to find people who are smarter than me; I only have to be smart enough to recognize who knows more than me.
