Book excerpt: Emergencies—landing a malfunctioning plane, resuscitating a heart attack victim, or avoiding a head-on car crash—all require split-second decisions that can mean life or death. Fortunately, designers of life-saving products have leveraged research and brain science to help users reduce panic and harness their best instincts. Life and Death Design brings these techniques to everyday designers who want to help their users think clearly and act safely.
