Alex P. Keaton.  Mike Flaherty.  Marty McFly.  You may enjoy a wave of nostalgia thinking of actor Michael J. Fox’s best-known roles, but he has much more to offer.  In Always Looking Up: The Adventures of an Incurable Optimist, Fox writes about the choices, challenges, and philosophies that have been a part of his ongoing battle with Parkinson’s disease.  He doesn’t sugarcoat his trials, but this is no pity party.  With both charm and passion, Fox narrates a recording that would go on to win a 2010 Grammy for Best Spoken Word Album.  Not only is this a moving tribute to a remarkable individual, it is a challenge to all of us to recognize the gifts of everyday life.
