About the Book: In this gripping blend of medical memoir and investigative reportage, Professor Kevin Fong explores the critical balance between safety, risk and decision-making in high-pressure environments. Drawing on his experiences with the Helicopter Emergency Medical Service and the NHS Covid-19 Strategy Unit, he reveals how the pursuit of zero harm can sometimes prevent lifesaving action. Through compelling real-life stories from medicine, aviation, spaceflight and military operations, Fong examines human error, crisis management, risk assessment and the consequences of split-second decisions. This thought-provoking book challenges conventional ideas about safety and explores how embracing calculated risks can improve outcomes in life-or-death situations
