One widely circulated concept to help set priorities is called the "Rule of Three":
1. Humans cannot survive more than three hours exposed to extremely low temperatures.
2. Humans cannot survive more than three days without water.
3. Humans cannot survive more than three weeks without food.
These three rules can be a foundation for any emergency. Pack accordingly.
