Rafael Gonzalez Maldonado is, among other things, a neurologist. Here he uses a new perspective to discuss Parkinson's disease, combining thorough knowledge with pleasant reading. He believes that scientific rigor should be accompanied by an esthetic sense, and that the truth, besides being true, is fun. These pages offer glimpses of the spirits that haunt the author (Gracian, Stevenson, Goethe, Leonard Cohen) and his more recent loves (mythology, emotional intelligence, poetry, shiping...); this is inevitable, because, after all, a man can only write the book he holds within."
