While healthy habits like exercise, social connections, and stress management are important for longevity, the author argues that individual actions alone are not enough. Environmental factors such as air and water quality, as well as the strength of a society's social safety net, also play a critical role in determining life expectancy and overall health.

Why it matters

This article challenges the common narrative that longevity is solely dependent on personal choices. It highlights how broader societal and environmental conditions significantly impact lifespan and healthspan, raising awareness of the need for policy changes and community-level interventions to support public health.

The details

The author outlines the "Great Eight" healthy habits that research has linked to longer, healthier lives, including exercise, social connections, a sense of purpose, mental stimulation, healthy eating, sleep, stress management, and avoiding smoking and excessive drinking. However, the author argues that these individual actions are not enough, and that environmental factors such as air and water quality, as well as the strength of a society's social safety net, also play a critical role. For example, air pollution from vehicles, factories, and wildfires can contribute to respiratory issues and premature death, while water pollution from agricultural runoff and lead pipes can also have deadly effects. The lack of a robust social safety net in the U.S., including fragmented healthcare and poor access to mental health resources, has also eroded American life expectancy, which now ranks 55th globally.

• In 2023, the U.S. ranked 55th in life expectancy out of 210 countries.
