How is it possible for a human to survive 9 days without food or water?

Surviving nine days without food or water is extremely rare and typically only possible under specific conditions, such as cooler temperatures and low physical activity, which can slow the body's metabolic demands. The human body can survive without food for several weeks by using stored fat and muscle for energy, but without water, survival is usually limited to a few days. In some cases, individuals may have access to small amounts of moisture from their environment, which could prolong survival. However, enduring such a situation poses serious health risks and is not sustainable long-term.
