"I don't mind going outside my comfort zone, but this was another level," global superstar Chris Hemsworth, known for playing Thor in Marvel's Avengers franchise, told TV GUIDE MAGAZINE about shooting the second season of this investigative series, in which he braves thrilling, high-stakes situations to test methods for living a longer, healthier life. Three themed episodes were filmed across six countries over two years. In "Brain Power," he learns to play the drums for a live performance with singer Ed Sheeran in Bucharest; in "Risk," the actor scales a nearly 600-foot climbing wall in the Swiss Alps; and in "Pain," he joins special forces training in South Korea. Hemsworth gets feedback from a returning expert, renowned palliative care physician Dr. B.J. Miller. He also meets new faces like freestyle motocross legend Robbie Maddison; cognitive scientist Maya Shankar; free solo climber and wingsuiter Steph Davis; and neuroscientist Abigail Marsh. Here, the actor reflects on his quest to make all of us sharper and stronger.
