"Sole Survivor" is a term often used to describe the only person who survives a catastrophic event, such as a plane crash or natural disaster. This individual may face unique psychological challenges, including survivor's guilt, as they grapple with the loss of others. In popular culture, the concept of a sole survivor is explored in various films and books, highlighting themes of resilience and the struggle to find meaning after tragedy. Notable examples include the movie Cast Away, where the protagonist, played by Tom Hanks, must adapt to life after being stranded on a deserted island.
