Wim Hof is able to run a marathon in 0 degree weather, with no prior endurance training, in a pair of boxer shorts and sandals.  He previously summited Everest and Kilimanjaro wearing only a pair of shorts.  This documentary provides a small glimpse of the raw unlimited power that meditative practices can bring to the human experience. Watch a TEDTalk by Wim here.
