4 "3 rules" of thumb

Memorize these. One day this information may save your life. "3 rules"

You can only survive: - 3 minutes without oxygen, - 3 hours without shelter, - 3 days without water, - 3 weeks without food So, if you are ever stranded, lost somewhere, these are your priorities: 1-air, 2-shelter (above all), 3-water, 4-food (suprisingly the least important). It may be hard to "sit and wait" but sometimes that is the best desicion you can make under extraordinary circumstances. Don't say "it will never happen to me", you can never know.
