In this thrilling three-part series from Academy Award-nominated filmmaker Darren Aronofsky’s Protozoa, Jane Root’s Nutopia, and Chris Hemsworth and Ben Grayson’s Wild State, Chris pushes himself further than ever — both physically and mentally — as he confronts some of life’s most universal challenges: pain, fear, and cognitive decline.

Filmed across six countries over two years, Chris tests his limits by drawing from cutting-edge science and the wisdom of elders to push himself like never before. With no previous experience, he learns to play the drums for a live performance with GRAMMY Award-winner Ed Sheeran in front of 70,000 fans; scales a dizzying 600-foot climbing wall in the Swiss Alps to break out of his comfort zone and embrace risk; and takes part in South Korean Special Forces training, enduring electrocution and pepper spray to confront his long struggle with chronic pain and reconfigure his response to it — all to uncover tools we can use today to live healthier, happier lives.

All episodes will stream Aug. 15 on Disney+ and Hulu and will air on National Geographic on Aug. 25.
