A story happened in America:

A couple went skiing. Unfortunately, they were caught in a snowstorm and were trapped in the mountains. The weather is very cold, there is no trace of life around them, and they have no food and warm clothes. After a day, the snowstorm continued, so they had to hide in caves and silently endure the cold and hunger.

The husband looked at his wife who was getting worse and worse and decided to continue looking for food outside. He went out, knowing that he could not find anything. After a while, he came back, and his wife found him covered in blood and his whole left arm was gone. The husband endured the pain and told his wife that he met a bear. The bear was killed by him, but his arm was bitten off by the bear. He said that he gave his wife a baked black thing, that it was bear meat for her to eat, and that he had already eaten it. A week later, the rescue team found them, the wife was saved, but the husband had left the world far away. By chance, a doctor found that the leftover bear meat was an adult man's left arm. The wife realized that the food that supported her for a week was her husband's left arm. A rescuer found a bloody stone and a pile of charred charcoal not far from the cave. It turns out that her husband hasn't met any bears (there are no bears in this area at all). He broke his left arm with a stone not far from the cave, then baked it and gave it to his wife, the person he loved.

He gave up his chance and right to live, leaving the opportunity to his wife and relatives.

A very sad story, a very touching story, but absolutely true.
