The “Rule of Three” should only be viewed as a general guide line. There are many exceptions to these rules. For instance the record for holding ones breath is 10 minutes, 17 seconds, the crew of a boat once lasted 8 days without water, and people have survived without food for over 50 days. In most survival situations though, there are three priorities that should be met: Food, Water and Shelter. Keep these priorities in mind.
The “Rule of Three” highlights the requirements for human survival and it goes as follows:
- Humans cannot survive more than three minutes without air.
- Humans cannot survive more than three hours without shelter.
- Humans cannot survive more than three days without water.
- Humans cannot survive more than three weeks without food.
