What takes more years off your life than smoking or obesity?

Being poor:

The average low-income person loses 8.2 years of perfect health, the average high school dropout loses 5.1 years, and the obese lose 4.2 years, according to researchers at Columbia University’s Mailman School of Public Health. Tobacco control has long been one of the most important public health policies, and rightly so; the average smoker loses 6.6 years of perfect health to their habit. But the nation’s huge high school dropout rate and poverty rates are typically not seen as health problems.
