A Nepali guide who was discovered crawling down Everest six days after he was last seen alive said he survived by "chewing ice" and eating a few chocolates he found in his pocket. Dawa Sherpa insists he didn’t “go missing" on the descent down, but instead was forced to "stay behind" after his oxygen ran out. His family, who thought he was dead, said they were “so happy” when they saw pictures of his rescue. Tap the link in @BBCNews’s bio to read more on the guide’s ordeal. #Everest #BBCNews
