The comedian Hannah Gadsby has been touring this summer with a show called “Body of Work.” She came to wide attention in 2018, with the Netflix special “Nanette.” It was a full-length comedy show, and, at the same time, a carefully structured critique of standup comedy which argued that comedians have to distort personal experience for the sake of a joke, inflicting a kind of violence on themselves and their audiences. Gadsby recently published a memoir about her breakout moment called “Ten Steps to Nanette.” The New Yorker’s Emily Nussbaum talked with Gadsby back in 2018, when “Nanette” had just been released. Plus, Patricia Marx tries the trendy relaxation technique called flotation therapy—formerly known as a sensory deprivation tank. But relaxing, Marx found, is just too stressful, and her microphone was the only thing that found peace.
