Priorities of Survival, Rules of 3
There are several rules basic to survival. They’re known as “survival rules of three“. You can survive 3 minutes without oxygen, 3 hours without shelter, 3 days without water, 3 weeks without food, 3 months without hope. I go into some detail on each in this video. Everyone has a different ability to cope with hardship and as a result some could last longer than others.
