William Trubridge has held 18 world records in the various disciplines of free diving. He spends much of his time living on Long Island in the Bahamas, home of the famous Dean's Blue Hole where many of the world records have been set. William and I talk about the rise of free diving as a sport, what it takes to become a champion and how to successfully manage the risks. We take a fascinating dive into the physiology of immersion to unravel just how humans can descend to great depths on a single breath.
