Join Our Campaign to Just Say Hello

Did you know one word has the power to make you live longer? We're partnering with Skype to improve the world—and your health—one new friend at a time. Watch as Oprah, Gayle, Jimmy Kimmel, Julia Roberts and others help us combat loneliness and demonstrate how a small gesture can make a big difference. Then, tell us about a hello you gave or received by posting to Twitter, Facebook, Instagram, or Vine using the hashtag #JustSayHello.
