Now that his only son is in college, Michael J. Fox finds himself grossly outnumber at home by his wife Tracy Pollan and their three daughters. "We even have a dog who is a girl," he jokes. "So I got a new dog - a Great Dane named Guss. Guss and I are the testosterone!"

The actor, most recently seen on the Emmy®-award winning series Rescue Me, is also an author whose latest book A Funny Thing Happened on the Way to the Future ... " is aimed at young adults and recent graduates. "However well you plan out your life and whatever courses you take and whatever degrees you get, your life is really going to get most interesting when it goes off the rails, when it blows up and something happens that you didn't expect - you have some loss or some misadventure," he explains. "If you're open to what happens next and you don't try to do something to change it - you just kind of accept it for what it is - you're going to learn something and your life will improve."

In Michael's life, for example, being diagnosed with Parkinson's Disease at age 30 changed everything. "[It's] not the way I thought my life was going to go," he says, "but so many things [came from that] -- with the foundation, with the way it made me reevaluate my life, the way it made me reevaluate time with my family and what my priorities were." His Michael J. Fox Foundation is now the largest private fund of its kind in the world and has invested more than $175 million in Parkinson's research. "The big lesson with all this stuff, if there are things that are important to us and causes that we care about - none of this stuff falls from the sky and it's really important for us to take the initiative and push things and to ask questions of people that we need to ask questions of, and inspire people that we need to inspire."

"You can do so much more than you think you can do," adds Rachael. "Every one of us can make a conscious choice to make a difference in our communities in each other's lives and it can start with something as simple as making pancakes for your neighbors, mentoring a kid on your block at something your good at, you can be an educator and a mentor which is another great thing!"
