Wim Hof is a staple in the biohacking community. The Vice Documentary from earlier this year does a great job of summing up his story. His wife committed suicide and it changed everything for him. This is a man who through his own amazing level of willpower is controlling the uncontrollable. He has summited Everest in a pair of swim trunks, run a barefoot marathon above the arctic circle and holds over 20 world records for other amazing feats. Whether or not you buy into his techniques there is something irresistible about his character.
