Chris and Xand continue their conversation about body odour with Matthew Cobb, Professor Emeritus of Zoology at the University of Manchester.

They explore whether it’s possible to predict how someone experiences an odour based on their DNA, and how our sense of smell compares to that of other animals.

Many people lost their sense of smell during the Covid-19 pandemic, bringing greater awareness to just how central this sense is to our everyday lives. They discuss the role that smelling ourselves and each other plays in everyday life, what happens when that sense is lost, and what support is available for those experiencing anosmia.
