7. Nurture friendships
A close network of supportive friends may help you live longer. A 2005 Australian study found that over a 10-year period, older people with close friends survived longer than those without. Interestingly, close relationships with children and other relatives didn’t affect survival rates. “We all need two or three really good friends—not Facebook friends or fair-weather friends, but people we can call when we’re having a bad day and they’ll care,” Buettner says.
Try this: Call a friend. As Buettner says, “Friends take effort. We need to invite them for dinner and remember birthdays.”
