A young man has stopped breathing in a supermarket toilet. A pedestrian with a nasty head injury won’t let the crew near him on a busy road. A newborn baby is worryingly silent. An addict urinates on the ambulance floor when denied a fix. This is the life of an ambulance paramedic. Jake Jones has worked in the UK ambulance service for ten years: every day, he sees a dozen of the scenes we hope to see only once in a lifetime. This is a memoir of the chaos, intensity and occasional beauty of life on the front lines of medicine in the UK.
