Researchers have found a link between education and life expectancy. Life expectancy in the US has been on the rise in recent decades, but the numbers are disproportionate. On average, those who continued education beyond high school have a life expectancy of 82. Those with 12 or less years of schooling have an average life expectancy of 75.

So what do books have to do with life span? Nothing really. Researchers attribute the difference to lifestyle. People with less education are more likely to have a lower income which can lead to subsequent health-related issues such as poor housing, crime, or lack of medical insurance. In addition, researchers feel tobacco usage may account for the discrepancy in life expectancy.
