For the past 100 years, life expectancy in the US has been on a relentless upward march. It was 69 when I was born in 1955. In 1994 it was 75.7. In 1998 it was 76.7. In 2002 it was 77.0. In 2006 it was 77.8. In 2010 it was 78.7. That’s when Obamacare was passed. In 2014 it was just 78.8. That’s the smallest 4-year increase since annual data began (in 1970).
