Surfer and filmmaker Kyle Thiermann explores a wide variety of people in his work. In this video he meets with accomplished big wave surfer and free diver, Mark Healey to discuss the dangers of the ocean. Healey is insightful about his craft. According to him it takes a complete commitment and passion to accomplish these things—you have to be fully engaged in the task at hand. He shows off his prowess in the water by holding his breath for three and a half minutes. It is eerie watching the footage of Mark under the water as he narrates. Either way, if you can hold your breath and stay calm for that long, congrats. You have lungs of steel.
