In 2019, John Hendrickson wrote a piece for The Atlantic about then-presidential candidate Joe Biden's life with a stutter. Hendrickson himself stutters – and in his new reported memoir, Life on Delay, he takes a closer look at his relationship with talking out loud. In this episode, Hendrickson tells NPR's Scott Simon about the physical discomfort that he and others experience when stuttering and how, beyond that, there are layers of mental work to be done to remember it's still worth it to keep speaking up.
