Why do so many of us get nervous when public speaking? Communication expert Lawrence Bernstein says the key to dealing with the pressure is as simple as having a casual chat. He introduces the "coffee shop test" as a way to help you overcome nerves, connect with your audience and deliver a message that truly resonates. After the talk, Modupe explains a similar approach in academia called the "Grandma test," and how public speaking can be as simple as a conversation with grandma.
