> I have not the slightest clue what you are on about
Wim Hof is known as 'The Iceman', and some studies done on the guy suggest he is capable of controlling his autonomic nervous system to control where his blood flows, so that he can handle extreme cold. I vaguelly recall he did Kilimanjaro in shorts, and he can sit in a tub of ice for an hour or so, swim in the Arctic, etc. Mental stuff.
If I remember correctly he does this through breathing exercises, something a bit like hyperventilating.
But I still am as clueless as to what the OP is on about as you are
