1. Remember: the brain cannot simultaneously monitor the situation around and what is happening on the smartphone

It seems to you that walking down the street is as familiar and not requiring special concentration as eating a sandwich, isn’t it? So why not combine such a simple action with correspondence on your smartphone?

In fact, the human brain is not capable of simultaneously processing two independent streams of information. He concentrates on only one of them at any given time.

Yes, the ability to quickly switch gives the appearance of multitasking, but in fact it is not. And if a sandwich doesn’t run away from you in those couple of seconds while you focus on your smartphone, then on the street, even in such a short time, you can be hit by a car, a cyclist, or you can collide with another passerby.

2. Keep in mind: rear-view mirrors do not always give an objective picture

It is important to know that the side mirrors of many modern cars are designed to be slightly convex on purpose. This is done in order to give the driver a larger view, the so-called spherical picture.

However, this property of mirrors has a drawback: they reduce the reflected objects, making them visually more distant. Remember before making a maneuver that the car moving behind you may actually be much closer to you than it seems.

3. Don’t Eat Snow Instead of Water Unless It’s Absolutely Necessary

If you’re out for a winter walk or hiking, try not to eat snow instead of water. Our body spends a large amount of energy on the transformation of substances from one state to another, so there may be a rapid overcooling of the body. Use snow only if the thirst is already unbearable, and you have no water and are not expected.

4. If you are choking, save yourself with the Heimlich method

The Heimlich maneuver is one of the most effective emergency procedures to use if a person has choked on food or an object and feels suffocated. In the classic version, this method requires the help of another person, but in extreme cases, you can use it alone.

To do this, clench your hand into a fist and place it just below the ribs, but above the navel. Place the second palm on top for reinforcement. Make a sharp and strong push towards the spine and slightly up. Repeat until you get rid of the stuck item.

5. Stock up on strong antihistamines when you travel to new places.

Even if you feel perfectly healthy and have never experienced an allergy attack, be sure to take a package of some kind of antihistamine medication with you on your trip. There is a possibility that a new environment, food, vegetation, insects can cause an allergic reaction.

6. In extreme situations, remember the rule of three

When you find yourself in an extreme environment, the most important thing is to properly prioritize and solve problems in order of their importance. To do this, remember the so-called rule of three. It states that the average person can only survive three minutes without air, three hours without shelter (under extreme weather conditions), three days without water, and three weeks without food.

7. If you get a penetrating wound, do not pull out the blade

If you have been stabbed with a knife or other sharp object, do not try to pull the blade out of the wound as quickly as possible. So you will get, in addition to damage to the internal organs, also profuse bleeding. Instead, try to minimize blood loss as much as possible and seek medical attention quickly.

8. If you need help, ask a specific person

You have probably seen situations when something bad happens to a person in a public place, such as a heart attack, but no one rushes to his aid. This is due to the well-known psychological phenomenon where a crowd of people is unable to take any action, because everyone thinks that someone else is about to step in and solve the problem.

Therefore, if you urgently need help, choose one person and contact him personally. In this case, you are much more likely to receive assistance than if you address everyone at once or remain silent, hoping for the compassion of the crowd.

9. Protect yourself with a bright flashlight in case of an attack

A small flashlight with a very bright directional beam can be a much more reliable method of protection than a can of gas or other means of self-defense. Especially if it happens at night or in a dark place.

A powerful beam of light aimed at the attacker’s eyes will blind him and give you a few precious seconds to retreat. It’s safe and completely legal.
