蜜芽传媒

Welcome to What鈥檚 Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore every aspect of our health and wellbeing.

In this special episode, recorded before a live audience at the Hay Literary Festival in Wales, Chris and Xand discuss the anatomy of the smile, its evolutionary origins and some of the health claims about smiling. Is smiling uniquely human? Can the simple act of moving our muscles to form a smile make you feel happier? And is smiling the same across cultures and genders? To find out, they鈥檙e joined by several experts and an African street dog named Jack.

Featuring Professor Ben Garrod from the University of East Anglia, Dr Magdalegna Rychlowska from Queen鈥檚 University, Belfast and Sinead Rushe from the Royal Academy of Dramatic Arts in London.
