"The will to survive" is a big part of this story. It sounds like the wife gave up. May her soul rest in peace. I don't fault her for wanting to give up. She lived a long purposeful life of 82 years and was facing the agony of frostbite and a long struggle to crawl out of the wilderness. I don't know that I would give up 20 feet from the car, but I understand it. I just hope her family can come to grips with it and be at peace.
