"When Oliver Sacks was twelve, a perceptive schoolmaster wrote: "Sacks will go far, if he does not go too far." It is clear that Sacks never stopped going--from his youthful obsession with motorcycles to the engagement with his patients that came to define his life. With unbridled honesty and humor, Sacks shows us the restless energy that drives both his physical and his cerebral passions. On the Move is the story of a brilliantly unconventional physician and writer who has illuminated the many ways that the brain makes us human."--Back cover.
