Book readers live an average of two years longer that those who don’t read at all. That’s the finding of a study out of Yale University. Researchers examined the reading habits of 3,635 people over the age of 50 and found that the ones who read up to 3 ½  hours a week were 17 percent less likely to die over 12 years of follow up. This was even after variables, such as health, education, and income, were taken into account.

It’s not clear why there’s the “reading advantage,” but researchers suggest delving into novels promotes cognitive processes, such as empathy and emotional intelligence, which can boost longevity.

So the next time you give a book talk, speech, or book launch use the line, “Read my novel. It could add years to your life!” It could make your book sales increase dramatically.
