Most people in the world speak more than one language and many countries have more than one official national language. But what is it like living as a polyglot? And what advantages can it bring to your health? Studies have shown that speakers of multiple languages get dementia later and even recover better after a stroke.

BBC journalist Victoria Uwonkunda describes what it was like growing up as a polyglot and how she deals with speaking multiple languages in her daily life. Turkish polyglot İclal Dağcı , who speaks nine languages, tells us how she uses music to learn languages she finds difficult.

Plus, Professor Frédérique Liégeois, a cognitive neuroscientist at University College London, explains the benefits speaking multiple languages has on your brain, and how it could help to maintain your brain health as you get older.
