Book excerpt: 'At the turn from our bedroom into the hallway, there is an old full-length mirror in a wooden frame ... This reflected version of myself, shaking, rumpled, pinched and slightly stooped, would be alarming were it not for the self-satisfied expression pasted across my face. I would ask the obvious question, "What are you smiling about?" but I already know the answer: "It just gets better from here."' Struck with Parkinson's - a debilitating, degenerative disease - at the height of his fame, Michael J. Fox has taken what some might consider cause for depression and turned it into a beacon of hope for millions. In Always Looking Up, Michael's Sunday Times bestselling memoir, he writes with warmth, humour and incredible honesty about the journey he has undertaken since he came to terms with his condition.
