Tristan Gooley seems like a cool guy. He has led expeditions on five continents, climbed mountains in Europe, Africa, and Asia, sailed small boats across oceans, and piloted small aircraft to Africa and the Arctic. He is the only living person to have both flown solo and sailed singlehandedly across the Atlantic, and he is a Fellow of the Royal Institute of Navigation and the Royal Geographical Society.

And just what have you done with your life?

Gooley joined the show this week to talk about his new book, The Lost Art of Reading Nature’s Signs: Use Outdoor Clues to Find Your Way, Predict the Weather, Locate Water, Track Animals—and Other Forgotten Skills In it, you'll find out how to use trees’ leaves as a compass, watch butterflies to estimate your altitude, and tell the time using the stars.
