Although the theories discussed on this topic appear to be a bit unfounded, there are many people in Europe and the United States who are preparing for "Judgment Day" and preparing various things in advance. Some people call them doomsday operators.

“End Times” based on religious teachings can sometimes become laughable. Although the theories discussed on this topic seem a bit unfounded, there are many people in Europe and the United States preparing for "Referee Day" and preparing various things in advance. Some people call them doomsday operators (preppers). Since the threat of artificial intelligence (AI) to human beings may be real, let us talk about doomsday survival strategies from a scientific perspective.

When the tools and services to protect yourself disappear, the minimum things you must first prepare are "water", "food", "shelter" (hiding place), "fire" and "clothing".

Human beings cannot survive without "water". Even if you are lucky enough to find a natural water source, it may not be contaminated by bacteria. To make drinking water safe to drink, boil it for at least 5 minutes to sterilize it and make it safe. It is also important to harmlessly transform toxic proteins through heat.

You should also be able to collect water from the plants. If you find a cactus, you can cut off a section and grind it out.

Additionally, snow cover can be a valuable water source, but depending on the situation, it can contain contaminants, so it needs to be used with caution. Squeezing water spilled into cloth, collecting water droplets on leaves, and collecting water accumulated in rock cracks are also important skills for survival.

Be careful of dehydrated lips and tongue, important fluids may be lost. When thirsty, it is also useful to use buttons and pebbles in the mouth to promote the secretion of "saliva" to help relieve thirst. Fortunately, even if you find a lot of water, don't drink it all in one go, but drink it bit by bit to allow your body to fully absorb it. Otherwise, it may develop symptoms of nausea and, in turn, expel water from the body.

Next up is "Food". In an emergency, you will inevitably end up eating insects and the like to survive. However, these organisms can be excellent foods, efficient in protein, vitamins, and minerals.

Capturing and eating wild animals is also essential.

However, when hunting and capturing prey, the degradation of meat proceeds rapidly as the lactic acid remaining in the muscles acts. In this case, if you cook quickly, you can minimize the adverse effects.

If the intake of vitamin C is insufficient for more than one month, the body's healing function will be weakened and the wound will not heal. This is because very little collagen and protein are needed for the body to regenerate. In this case, you can take as much vitamin C as a glass of orange juice by drinking tea of ​​boiled spruce (cedar) twigs and leaves.

One of the easiest creatures to catch in the wild is the rabbit. However, since rabbits are fat-poor creatures, they need to absorb fat in a different way. Modern society can easily consume fats from butter and milk, but butter and ice cream are not available in the place where we survive. In this case, it is a good idea to use acorns instead of fruits.

Acorns contain large amounts of fat, and in many cases, they are not poisonous. However, since tannin has a bitter taste, do not eat it directly. First boil it for about 2 hours, grind the fruit, knead the powder and eat it as bread, etc. In addition to acorns, dandelion and maple seeds can be eaten in the same way.

When the ocean is close at hand, fish are an important source of nutrition.

In addition to fish, seaweed should also be considered a valuable source of nutrients. It's good cooked, steamed, grilled, or even eaten raw. It goes without saying that shellfish and other fish are prized foods.

When animals are captured and meat is obtained, the main method of consumption is "roasting". The usual method is to stick the meat on a wooden or iron rod and put it over the fire, but it would be better if you remember how to "steam" the meat by drilling a hole in the ground.

Dig a hole in the ground, put the burnt stones in, and sprinkle wet vegetables and seaweed over it.Then put the meat and water on top, and you can use the heat of the stone to make steamed dishes.

As a tool for starting a "fire", if there are matches and lighters left, this is the best. However, over time, when any of them will run out, you should know that you can light a stone and create a spark at such a time. Pearlite ( Pyrite ) is declining around it and should be retained as this also becomes a valuable ignition source. Of course, the method of using a magnifying glass and sunlight to emit is also very useful.

If you can light a fire, keep it alive with bark, twigs, dried algae, etc. By doing this, you can keep the fire going for as long as possible.

However, it is strictly prohibited to burn fire in a closed space to protect yourself from enemies, as it can become carbon monoxide poisoning and lose your life.

This is a small cave that can be used as a "shelter". In addition, by processing the branches into columns, huts and roofs, an easy-to-use space can be ensured. You can also keep drinking water safe by making devices to prevent rainwater from falling on your roof.

"Clothes" are important to protect yourself from the cold of winter. However, because the weather is very cold, if it is too thick, it will promote sweating and lead to dehydration, so it is best to be slightly colder. To ensure freedom of movement, avoid wearing slim-fitting jeans and it is convenient to prepare clothes with many pockets. Additionally, when socks get wet during the cold winter months, they can cause frostbite. To avoid this, one way you can increase water resistance is to coat the inside of your socks with animal fat. Of course, this is one of the best ways to beat the cold with feathers.

In fact, the most important thing is to remember this knowledge.

In the event of a disaster or "Referee Day", you will most likely be without internet access and unable to search for necessary information when speaking of Isa. If you are used to the specific society of the Internet, you will think this is normal, but sometimes it is important to know in advance what original life is like and think in advance.
