In an age of Facebook, Twitter, Snapchat, online dating and whatever you're having yourself, it can sometimes be difficult to switch off and take a look around to see what's actually happening in the world. This documentary sees technology journalist Adrian Weckler meeting self-confessed social-media addicts of a variety of ages in Ireland, and setting them the challenge of doing a digital detox for a full week. He also gets the views of a wide range of social-media users and experts about how this new technology is changing people's relationships, brains and behaviour.
