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 nearly 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.Joining him on the third episode of this transformative journey are neuroscientist and Professor Abigail Marsh and freestyle motocross legend Robbie Maddison. Inspired by his children’s carefree risk-taking, Chris pushes his limits and learns from experts how exposure therapy and Flow — a state of hyperfocus — can improve mental and physical health and showing how taking risks as adults can lead to a happier, healthier life.
