Michael J. Fox, who was diagnosed with Parkinson’s disease in 1991 and starred on Spin City until 2001, is planning a return to television with a special on the effects of optimism. Michael J. Fox: Adventures of an Incurable Optimist, airing May 7 on ABC, will look at the literal power of positive thinking, and share details from Fox’s own life. For the special, the actor, husband, father, and Parkinson’s activist will travel to Bhutan, the tiny Himalayan nation so invested in it’s people’s well-being that it actually monitors the country’s Gross National Happiness.
