You could just as easily freeze in a shelter without a way to hydrate and get warmth into your system. Shelter can be made without cutting tools in most cases... fire is important, no argument.... so is a knife. Without a means to melt, heat and contain water.... you are pooched in cold, wet/snowy environments. Go 24hrs without hot water in the mountains. Everytime you drink from a stream you are lowering your core temperature. Maybe your experience tells you different.... mine tells me to work from the inside, out. If you can get out of the wind and direct rain... there's not much a hot cup of tea can't cure.
I think we are getting to the same place... just taking alternative routes.:thumbup:
