I have a confession to make (but it’s not such a bad one). TED, a worldwide organisation which brings together speakers on education, business, science, tech and creativity, has a Youtube channel entirely devoted to short educational videos on a wide range of topics.  My confession is that I’ve been slightly addicted to watching them lately, finding myself lost in a spiral of absorbing information on everything from how you digest food to how people lived in ancient Rome. They’re fascinating, and I strongly suggest you try them out.
