With many tens of thousands in the United Kingdom and over a million worldwide dead at the hands of Covid-19, away from the headlines, those neglected have often been the sufferers of today's long-term conditions. Conditions like diabetes, heart disease, cancer and depression comprise the modern plagues that kill millions and burden many more with years of lingering disability. We know that society must work to prevent these common diseases; however, as governments dither and tinker with health policy, the modern plagues spread further and further into society. Saving sick Britain lays down a challenge to every British citizen, institution, policymaker, and scientist. How do we halt these epidemics and reduce the numbers of people who must endure them for decades? This pressing question requires us to think afresh about both prevention and what 'health' really means. In this timely book, Yuille and Ollier envisage a society in which the health of citizens is protected at all costs. Proposing extensive public policy reforms at both the local and national levels, this book outlines a plan to transform public policy in pursuit of a national 'Health Society.' Every workplace, employer, community organisation, and citizen has a role to play, the authors argue, and we must act now to halt the systemic risk these plagues pose to society.
