Sad news for all of us: producer Rachael Cusick— who brought us soul-stirring stories rethinking grief (https://zpr.io/GZ6xEvpzsbHU) and solitude (https://zpr.io/eT5tAX6JtYra), as well as colorful musings on airplane farts (https://zpr.io/CNpgUijZiuZ4) and belly flops (https://zpr.io/uZrEz27z63CB) and Blueberry Earths (https://zpr.io/EzxgtdTRGVzz)— is leaving the show. So we thought it perfect timing to sit down with her and revisit another brainchild of hers, The Cataclysm Sentence, a collection of advice for The End. To explain: one day in 1961, the famous physicist Richard Feynman stepped in front of a Caltech lecture hall and posed this question to a group of undergraduate students: “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence was passed on to the next generation of creatures, what statement would contain the most information in the fewest words?” Now, Feynman had an answer to his own question—a good one. But his question got the entire team at Radiolab wondering, what did his sentence leave out? So we posed Feynman’s cataclysm question to some of our favorite writers, artists, historians, futurists—all kinds of great thinkers. We asked them “What’s the one sentence you would want to pass on to the next generation that would contain the most information in the fewest words?” What came back was an explosive collage of what it means to be alive right here and now, and what we want to say before we go.

Join Ender Darling, the infamous "Tumblr Bone Witch," alongside TikToker John's Bones, and former morgue manager Cedric Lodge as they dissect the gripping tale of online human remains trading. They discuss the ethical quandaries surrounding bone collecting and how it connects to colonial exploitation. Caitlin Doughty offers her insights on death rituals, while the group unpacks the chaotic fallout from Ender's controversial actions and the strange intersection of social media and spiritual practices. It's a spooky dive into bone theft and cultural complexities!

Caitlin Doughty is a mortician who would like to put herself out of business. Our corporate funeral industry, she argues, has made us forget how to offer our loved ones an authentic sendoff. Doughty is the author of Smoke Gets in Your Eyes: And Other Lessons From the Crematory. In this installment of the Freakonomics Radio Book Club, she is interviewed by guest host Maria Konnikova.
