EVENTS DESCRIBED ARE BASED on Dr. Kalanithi’s memory of real-world situations. However, the names of all patients discussed in this book—if given at all—have been changed. In addition, in each of the medical cases described, identifying details—such as patients’ ages, genders, ethnicities, professions, familial relationships, places of residence, medical histories, and/or diagnoses—have been changed. With one exception, the names of Dr. Kalanithi’s colleagues, friends, and treating physicians have also been changed. Any resemblance to persons living or dead resulting from changes to names or identifying details is entirely coincidental and unintentional. l4Ot8K2CIEGSpbk8TxqDZE1dypMFdELkd87ytW2hkPj+l8YEUGLx1YRW1LpObBhN
