Don’t you just love Michael J. Fox? Check out Fox on the March 31 Oprah Winfrey Show, when he’ll sit down for an interview to talk about Parkinson’s disease, finding a cure and his new book, “Always Looking Up.”

Michael J. Fox tells Oprah that his disease is “like having a 4-year-old climbing on you all the time… and so whatever you’re trying to do, you’ve got this 4-year-old and you’re … just trying to be patient and focus on what you need to do.”

Michael J. Fox talks about his book, Always Looking Up, and how he hasn’t been defeated by Parkinson’s disease.

Fox tells Oprah, “I’m a dad, I’m a husband, I’m an activist, I’m a writer and I’m just a student of the world. This is one fact of my life, but it’s not the totality of my life. It doesn’t define me.”
