Watch this fascinating video about Wim Hof. It is a good reminder about the unexplored potential of our mind. Come to think of it, I was first attracted to Buddhism because of mystical aspects and seemingly supernatural abilities that can be achieved by training the mind. For example, one of the first Buddhism related books I read was one by Alexandra David-Néel's (1868-1969). In it, she describes people being able to withstand extreme temperatures without clothing and also an ability to travel long distances in a short time.
Wim Hof's exercises are described here. By the way, some of the sensations described in the video - tingling, euphoria type feeling - are very similar to what one might experience doing Vipassana meditation.
