I highly recommend listening to the Tim Ferriss’s podcast with Wim Hof. He is a walking miracle. Wim’s nickname is the Ice Man. He holds the world record for the longest time spent in an ice bath and swimming in freezing cold water. I was very inspired by him, not only because he’s capable of super-human physical feats, but because he does it while being incredibly kind and happy—which is not easy to accomplish.
