Why do we laugh more when we’re with others? Are humans the only animals that laugh? Does ‘laughter yoga’ actually do anything? We're delving into the neurobiology, evolutionary history, and health effects of a good old chuckle.

Live from the Hay Festival Winter Weekend, Marnie Chesterton is joined by laughter expert and neuroscientist, Professor Sophie Scott, and an expert in making people laugh, comedian Miles Jupp, in this side-splitting panel show.
