http://people.com/human-interest/woman-a...e-says-sheriff/A Pennsylvania mother survived more than a day out West in snow and freezing temperatures by eating pine tree twigs and drinking her urine...Karen, who had taken wilderness survival training classes, hiked about 30 miles for 30 straight hour. Searchers found Karen curled up in a bed in the cabin, so exhausted from her cross-country trek through and over snow as deep as 3 feet she couldn’t make a fire, he said.
I can understand chewing on pinetree twigs, might get some calories from them. But the part of urine-drinking...? If the trek was so exhausting then taking a handfull of snow now and then to keep hydrated should not be a problem since the body produce plenty of heat because of the exhausting trek through snow.
As I understand it, eating snow should not be done if you are staying put in one place and not moving.
Or am I thinking completly wrong?
