You may live longer than people who don’t. That’s according to research from UC San Diego. But there IS a catch: The researchers found, you’ll only extend your life if most of your interactions are with people you’re already close to in real life. So, have a Facebook Messenger chat with your favorite cousin on your lunch break, or post old college photos on a friend’s page for “Throwback Thursday.” The longevity benefit you get from Facebook is the result of connecting with people in a real way. So, just like face-to-face socializing can reduce stress and help us live longer – so can REAL Facebook friendships.
