A.J. Jacobs (@ajjacobs) is a bestselling author, journalist, and human guinea pig. He has written four New York Times bestsellers, including The Year of Living Biblically (for which he followed all the rules of the Bible as literally as possible) and Thanks a Thousand (for which he went around the world and thanked every person who had even the smallest role in making his morning cup of coffee possible). He has given four TED talks with a combined 10M+ views. He contributes to NPR and The New York Times and wrote the article “My Outsourced Life,” which was featured in The 4-Hour Workweek. He was once the answer to one down in The New York Times crossword puzzle. You can find my 2016 interview with A.J. at tim.blog/aj.
