Watch Brain Games Season 4 Episode 2 Online

We all have things we say we can’t live without — coffee, smartphones, social media... But do we really need all those things, or on some deep level are we addicted to them? In this episode we’ll put you through a series of games and experiments designed to reveal how, like it or not, we’re all addicted to something, and why some addictions might be the best thing that ever happened to you. Learn what one of the most addictive sounds in the world is, why you can’t stop checking your phone, and why that awful pop song is still stuck in your head.
