Subscribe to BBC Ideas 👉 https://bbc.in/2F6ipav In this video, we explore three things you probably don't know about your gut. We start by explaining what's actually happening when you get butterflies in your stomach. We then ask if you should eat local yoghurt when you go on holiday. And finally, the bizarre-but-true way in which a parasite called toxoplasma gondii (or toxo for short!) can influence the behaviour of a mouse. It turns out one-in-four humans carry toxo too. Could it be impacting human behaviour? There's lots more research to be done. Professor of Biomolecular Medicine, Jon Swann explains all.
