Fearless

In “Fearless,” co-hosts Alix Spiegel and Lulu Miller explore what would happen if you could disappear fear. A group of scientists believe that people no longer need fear — at least not the kind we live with — to navigate the modern world. We’ll hear about the striking (and rare) case of a woman with no fear. The second half of the show explores how the rest of us might “turn off” fear.
