A 2016 Yale University study found that people who read books lived about 2 years longer than those who don’t. Although the study found a correlation between reading and increased lifespan, the researchers did not identify the cause.
However, according to Josie Billington at the University of Liverpool, “Reading not only helps to introduce or reconnect readers to wider life systems and more broadly shared meanings. It can also remind people of activities or occupations they once pursued, or knowledge and skills they still possess, helping to restore their sense of having a place and purpose in the world.”
Moral of the story: Cozying up with a book-a-day keeps the Grim Reaper away
