We owe a lot to animals, and it's time to explore how they live and what we can still learn from them. A better understanding of how humans coexist with millions of other species could lead to incredible medical advances that could help people and animals. While millions of years of evolution have taught us to cope with everyday challenges, when severe illness occurs, doctors, including Dr. Matt Morgan, are exploring completely different strategies to keep patients alive. As a critical care physician, Morgan deals with critically ill patients whose organs are failing and life is fading. Some patients can only be saved with the help of unique technologies and drugs. However, these technologies only became possible through observing how different species of animals adapted to life's challenges. Matt Morgan takes readers on a journey to show them how the greatest advances in human medicine were made possible by understanding the mechanisms of animal survival. It tells how various creatures breathe, eat, sleep, reproduce and die. Real-life stories of critically ill patients illustrate the connections between animal behavior and diagnoses, drugs and technologies from human medicine.>
