Actor Michael J Fox is grateful for his Parkinson's Disease, calling it "a gift." The Back To The Future star has accepted his shaking will only get worse unless a cure is discovered, but he insists his life is richer for Parkinson's. He says, "It's a progressive disease. I'm not gonna get any better. For me, unique to my situation, it's a gift; it's a gift that keeps on taking but it's a gift. I wouldn't go back. "The path it's put me on has been so amazing."
