Crying is a universal human experience. We can shed tears of joy, laughter, and sorrow - some of us even weep cutting onions. But what exactly are tears, and why do some of us cry more than others? 

Emma Kennedy talks to Ad Vingerhoets, author of Why Only Humans Weep and Emeritus Professor of Social and Behavioural Sciences at Tilburg University, and Tom Lutz, Professor and Chair of Creative Writing at UC Riverside and author of Crying, to find out.
