12. Water on the beach is too far from the shoreline.
When the waterline is abnormally far from the shore, this is a sign of a tsunami. If you notice this somewhere, you should warn everyone around and run.
Unfortunately, in 2004, people didn’t pay attention to this sign before a tsunami in the Indian Ocean. Almost on the entire shore was exposed and people went out to collect fish and shells. And children were the most interested. However, there were people on 2 beaches that knew about this fact: a 10-year-old English girl named Tilly Smith and biology teacher John Chroston. They managed to save the lives of many people that day.
13. The rule of 3
If you ever find yourself in a critical situation, you should remember these numbers that can be used to describe the survival abilities of an average person:
- 3 minutes without air;
- 3 hours in extreme temperature;
- 3 days without water;
- 3 weeks without food.
So, if you can’t get your priorities straight, the chances of surviving are much lower.
