    Do Animals Have Rituals Around Death?

    Listener Ross Wintle, driving past a cemetery near his home, wonders if animals other than humans have rituals around death? Barbara J King, professor emerita of anthropology at the College of William and Mary and the author of How Animals Grieve reports that when it comes to animals and death, you’ve gotta look at elephants. However there are also some interesting reports about magpies, red foxes and dolphins showing some interacting with the dead in their groups. Appropriately in a Day of the Dead episode, The Completely Optional Knowledge podcast helps us understanding that death is a bit more universal experience in the animal kingdom than just to humans.

    Why Do We Laugh At Pain?

    Listener Matthew Hollingshead, a skateboard enthusiast, asks why it’s so funny to watch people get hurt. We’re not necessarily talking about critical injuries, more like America’s Funniest Home Videos style failures, pain, and embarrassment. Caleb Warren, an Assistant Professor of Marketing at the University of Arizona helps us answer this question and feel a little better about finding joy in other people’s “hilarious misery”.
