This obviously written by someone who has never been forced to take ice cold showers because of lack of options. Oh yes your body will adjust and won’t feel it as much…at first. Then you start to realize that you are sending your body into hypothermia and you don’t feel anything because your body is shutting itself down. But after awhile even that isn’t enough to stave off the cold that is killing you and then the shivers start uncontrollably, leading to chattering teeth and blue lips.
Sure there is Zen in dying but is it really necessary?
