 In this age of social media, a new report finds more people around the world are actually feeling more lonely. More than one in five people, 23% worldwide, tell Gallup that they felt loneliness a lot of the day yesterday. Research has shown that when people feel lonely, it makes other issues like sadness, stress, and anger even worse. Loneliness is a big issue in many African nations, according to the Gallup survey, less so in Kosovo, Estonia, and Vietnam. I'm Rory O'Neill.
