In this episode of "No Stupid Questions," hosts Stephen Dubner and Angela Duckworth revisit their very first conversation. They tackle two intriguing topics: will the handshake fade away in a post-pandemic world, and why do we struggle with uncertainty despite it being a long-standing part of life? Duckworth suggests that the handshake might be on the decline due to its potential for spreading germs and proposes alternatives like saluting or bowing. The duo also delves into the reasons behind our discomfort with uncertainty, discussing its psychological effects and exploring how embracing "positive surprises" can help us shift our perspective on the unknown.
