Three top academics, three dangerous ideas and your host comedian Susan Morrison. Tonight Professor Alan Gow (Heriot-Watt University) is looking for the simple things that could help us stay sharp as we age. Dr Imad Faruque (Heriot-Watt University) wants to know why he can’t be in two places at once like the quantum particles he’s made of. And Dr Kat Rezai (Edinburgh Napier University) asks if Instagram’s #loveyourself trends actually promote #selfloathe.

Part of the Cabaret of Dangerous Ideas programme.
