The Longevity Audit

Most people are looking for dramatic health answers in the wrong places. They search for the supplement that will change everything, the diet that will fix everything, the morning routine that will optimise everything. Meanwhile, the real damage to their long-term health is happening somewhere far less glamorous: in the bedroom that is slightly too warm for deep sleep, in the desk chair they have occupied for ten hours straight, in the food environment that has quietly reorganised their eating without a single conscious decision being made. The Longevity Audit is a clear-eyed, evidence-grounded examination of the ordinary daily conditions that shape how well the body ages. Not the dramatic vices. Not the obvious bad habits. The patterns so familiar they have stopped registering as patterns at all. Drawing on research in sleep science, stress physiology, environmental health, metabolic medicine, behavioural psychology, and the science of social connection, Frances Kelly builds a systematic account of the hidden forces eroding healthspan in the lives of people who consider themselves broadly healthy. Chronic sleep restriction. Sedentary working days. Ultra-processed food environments. Unresolved stress physiology. Indoor air quality. The loneliness that medicine rarely treats as a risk factor. The alcohol habit cultural normalisation has made invisible. The early warning signals the body has been sending for years that nobody stopped to read. Each domain is examined with the same unflinching clarity: what is actually happening, why it has been allowed to continue, and what can realistically be done about it. The final section of the book delivers a practical, domain-by-domain audit framework that readers can apply to their own homes, habits, routines, and environments, not as a dramatic overhaul, but as the kind of honest structural reckoning that produces genuine and lasting change. The Longevity Audit is for people who are tired of being told to optimise, hustle, and biohack their way to better health. It is for people who want to understand what is actually happening in their ordinary daily life and do something real about it before the cost becomes unavoidable. Intelligent, urgent, and deeply practical. A book that changes what you see when you look at your own life.
