I love the irony. I'm perceived as being really young and yet I have the clinical condition of an old man.

I mean, I enjoy my work as an actor. But to make a difference in people's lives through advocacy and through supporting research - that's the kind of privilege that few people will get, and it's certainly bigger than being on TV every Thursday for half an hour.

Life is the power that's greater than I can ever comprehend.

I have now is whenever my kids say, "Can you look at this?" or "Can I ask you something?" or "Can you come here for a minute?" no matter what I am doing, I say yes instead of saying, "Just a sec." They never abuse the privilege, and I never once regretted it. What they took me away to do was never less important than what I was doing already.

Just as Parkinson's isn't a big topic of conversation in my house, neither is my career.

I still play hockey every now and then, and I still golf. But my biggest exercise is walking my big dog in the park every day.

The story is a testament to the consolations that get me through and give meaning to every area of my life.
