Extra Life: A Short History of Living Longer

This book explores the remarkable increase in human life expectancy over the past century.

In 1920, global life expectancy was just over forty years, but today it has more than doubled.

Steven Johnson delves into the factors behind this progress, including vaccines, reductions in famines, and improvements in public health.

The book tells the story of cooperative innovation, public support, and collaborative networks that have driven these advancements.

It also discusses future challenges, such as the impact of COVID-19 and global threats like climate change, and emphasizes the importance of continued public health efforts to ensure the benefits of extended life are shared by all communities.
