Disgust is something that we all experience, but what purpose does it serve? And what role does it play in our moral judgements?

Mike Williams speaks to the \u2018disgustologist\u2019 Val Curtis about how revulsion protects us from disease and learns how disgust can be used \u2013 and abused - as a political weapon.

He tests the limits of his own disgust, finds out what it\u2019s like to be the object of someone else\u2019s disgust and explores the idea that there is \u201cwisdom in repugnance\u201d with philosopher Steve Clarke.
