Steven Johnson: "Extra Life: A Short History of Living Longer"

How did humans (roughly) double life expectancy in the past 100-150 years? It wasn't accidental. And it wasn't as simple as a lot of folks might think. In "Extra Life", author Steven Johnson tells (as he always does) a very entertaining and important story about why we're living longer and what we can do to extend that welcome trend.
