For much of the past century, life expectancy increased. However, this trend is reversing in several high-income countries, such as the UK and US. While the wealthy pursue longevity through technology and individual optimization, this approach ignores broader societal factors affecting health. Obesity rates are soaring globally, clean air is scarce, and mental health issues are rising. The author, a public health scientist, recounts her personal attempts at health optimization through diet and exercise, highlighting the limitations of individual efforts. Research on regions with high life expectancy (Japan, South Korea, parts of Europe) reveals that healthy living is normalized through government policies and cultural norms, rather than individual choices. The UK's large diet industry contrasts with Japan's smaller one, demonstrating the impact of food environment. While individual choices matter, the author emphasizes the importance of collective responsibility. Policies that prioritize nutritious food, active cities, clean air, preventive healthcare, and public water provision are crucial. The conclusion highlights the need for a shift from individual responsibility to collective action, emphasizing the role of public policy and infrastructure in achieving longer, healthier lives.
