Survival and The Rule of Threes

Survival Rule of 3 and Survival Priorities

For real survival situations it is better to remember and prioritize by the four levels of the Survival Rules of 3:

• You can survive for 3 Minutes without air (oxygen) or in icy water
• You can survive for 3 Hours without shelter in a harsh environment (unless in icy water)
• You can survive for 3 Days without water (if sheltered from a harsh environment)
• You can survive for 3 Weeks without food (if you have water and shelter)

The main point of these rules are to concentrate, and focus on the most immediate task or problem you’re faced with first.

This all related to the Five Basic Survival Needs.
