Though 50-year-old Michael J. Fox is hardly an invalid, he has suffered from Parkinson’s disease since 1991 – the year his oldest son turned 2. He adores his wife, Tracy Pollan. “Tracy's big challenge is not having a Parkinson's patient for a husband,” he told Good Housekeeping. “It's having me for a husband. I happen to be a Parkinson's patient.” Here Pollan and Fox attend the book launch party for Ali Wentworth's “Ali In Wonderland” in February.
