The human body is a great machine. Our anatomy is the result of millennia of adaptation to the changing environment of the earth, which has made us one of the most complex forms of life. And while advances in medicine in recent centuries have allowed us to explore the nature of the human organism in detail, we never stop discovering new components and processes in our bodies. In addition, one would never have thought that some of these components would exist in earlier times. From explosive elements to cosmic things, here are some of the strangest, most amazing, and mostly unknown things that make up your body.

Alcoholic beverages are among the most commonly consumed beverages in the world. Around 36 billion liters of alcohol are currently consumed worldwide each year, which is enough to fill more than 14,000 Olympic pools. So it is clear that alcohol and people are closely related. In fact, they seem to be so interconnected that the human body produces its own alcohol at all times.
Ethanol is a naturally occurring type of alcohol that arises after the fermentation of organic substances and is the alcohol in alcoholic beverages. Bacterial populations in the mouth and intestines can endogenously produce ethanol in the human body. In addition, bacteria and yeast ferment carbohydrates such as sugar in the gastrointestinal tract. This process produces small amounts of ethanol, which is then released into the bloodstream.
According to several studies, a healthy and sober person generally has up to 0.8 milligrams of the body's own ethanol per liter of blood. Methanol, another type of alcohol, has also been found in human blood at concentrations of 0.6 milligrams per liter. Fortunately, these values are too small to be easily found in the blood and cause legal problems for those affected.
However, some people do not have it so easy, especially those who suffer from conditions such as the so-called "auto brewery syndrome" (ABS). In such circumstances, a person's digestive system is overflowing with fermentation-producing bacteria and fungi that can produce large amounts of alcohol from foods rich in sugar. People with ABS can consume more than four grams of alcohol per liter of blood until they are always drunk without alcohol. 
Ozone is an unstable substance. Ozone consists of three oxygen atoms and usually breaks down into simpler molecules within minutes. For this reason, the ozone gas in the atmosphere has to be replenished continuously and would almost disappear if it were not for certain ozone-generating sources. Ultraviolet radiation, thunderstorms, and human activity produce most of the ozone that is present on Earth. Your body also helps.
Almost two decades ago, scientists discovered that the human body's immune system produces ozone to combat biological threats. Our body contains a type of cells called neutrophils, white blood cells that are coated with antibodies and travel through the body to eliminate infectious bacteria and fungi. To do their job, neutrophils feed their antibodies with high-energy oxygen molecules. The antibodies then convert such molecules to ozone, which is useful for eliminating invasive bacteria. Neutrophils devour the foreign microorganisms and bombard them with the newly created ozone molecules in order to destroy them.
Since almost three quarters of our body's white blood cells are neutrophils, the amount of molecular ozone that is produced in every human being is significant enough. However, this is not a good thing – high concentrations of ozone are harmful. At a height of 25 kilometers above the earth, ozone forms a gas layer that protects the life of the earth from sunlight. However, near the ground, ozone contributes to air pollution and is one of the main components of the so-called "smog". And in the human body, ozone breaks down cholesterol and forms toxic molecules that accelerate the development of diseases such as arteriosclerosis and arthritis. 
For humans, cyanide is an extremely toxic chemical compound. It kills in a short time by preventing cellular respiration in the organism. The lethality of cyanide is more than proven. It has been used as a chemical weapon over the centuries to kill countless people. For this reason, it is surprising to know that cyanide occurs naturally in the human body itself.
Every day, different concentrations of cyanide get into our body because the chemical is contained in the air, water and food. In fact, foods like apples and spinach are carriers of cyanide. However, there is no need to panic – such concentrations are extremely low and are on the order of a few micrograms per plant (according to the record, one microgram corresponds to one millionth of a gram). In contrast, 0.1 g of cyanide is required to kill a person with an average weight of 70 kg.
Cyanide is also produced by our body. For example, chemical processes in saliva create cyanide gas in our throat, which is then expelled through breathing. It is estimated that a healthy person can contain up to 50 micrograms of cyanide per 100 grams (3.5 ounces) of tissue at any one time. However, such a connection does not accumulate in our body. Most of it is processed in the liver and excreted in the urine. Another part is converted into carbon dioxide by our lungs and, like the cyanide gas mentioned above, is released with every breath.
The processes responsible for the absorption, production and detoxification of cyanide in the human organism are quite complex. We have to thank our bodies for tacitly rid themselves of such deadly poison. 
7 Radioactive elements
All types of radiation in excessive amounts are harmful to humans. For example, even if the ultraviolet radiation does not try to burn our skin, the ubiquitous background radiation will still force us to get cancer. But did you know that some radioactive substances are also found inside?
A radioactive element in our body is thorium, a heavy metal that is used in electronic devices. While we ingest small amounts of thorium through food and water every day, it usually leaves the body within a few days.
Another of the most notorious substances we carry is uranium. It is a heavy, highly radioactive element that occurs naturally on the entire planet. As you may know, they have been used primarily in nuclear reactors and weapons of mass destruction. Studies show that an average adult has 22 micrograms of uranium in their body and can absorb about five micrograms daily. The main sources of uranium intake are food – especially unwashed vegetables – and water.
As soon as the uranium is present in the body, it can enter the bloodstream and deposit there in various organs and remain there for a few months until it is expelled from the body. Two thirds of the used uranium is deposited in our bones.
We should also mention potassium-40, a radioactive isotope of the potassium element that we ingest through many foods, but which is still beneficial for the human body. As you can see, we are quite radioactive. But don't be alarmed; you are unlikely to trigger a nuclear explosion just by sneezing. 
However, not everything in your body has to be dangerous or radioactive. There are also valuable elements in you that make you economically valuable by nature. Even so, it is not advisable that you try to get them out of your body to sell them.
First, we have gold. Most of the average person's gold is in their blood, with gold accounting for 0.02 percent of it. Overall, the human body contains 0.2 milligrams of gold, which is enough to make a cube of pure gold 0.22 millimeters (0.008 inches) in size. We also contain silver, another precious metal with low toxicity to humans. An average person consumes up to 88 micrograms of silver a day, which is the weight of some grains of sand.
But that's not enough to be valuable, is it? Well, researchers have found that human feces also contain gold particles and other expensive metals. A kilogram of human waste can contain a maximum of four grams of copper, silver, vanadium and gold. With that in mind, it was estimated that one million people's wastes could be worth $ 13 million.
Even if you didn't know it, your body was always a money machine. The problem, of course, is to mine your own precious metals in order to profit from them, as you may have to use evil methods to gain them. 
5 Hard drugs
It is common knowledge that the human body makes its own versions of some common medicines. For example, our bodies produce endocannabinoids, molecules that resemble the chemicals found in marijuana. Our brain also produces chemical compounds called endorphins, which have the same analgesic effects as morphine. But the human organism can of course also develop other drugs that would be life-threatening and completely illegal in sufficient quantities.
Such a drug is called dimethyltryptamine or DMT. This medication is usually extracted from certain South American plants and can be drunk, smoked or injected. DMT produces serious hallucinogenic effects, with users claiming to have traveled to other worlds or met divine beings after taking the drug. However, there is evidence that the human brain regularly produces small amounts of DMT. It is believed that the drug could be released in deep sleep or near-death experiences in the body.
Another man-made drug is a substance known as GHB, sometimes referred to as "liquid ecstasy". This substance has very different uses; Bodybuilders take it up to build muscle, while doctors prescribe it to treat sleep disorders. But GHB can be very dangerous if not used properly.
Among other things, taking GHB with alcohol can kill a person or leave them in a coma. For this reason, it is surprising to know that our body naturally contains the drug, albeit in tiny and harmless amounts. GHB occurs in many tissues of the body, in the blood and also in the brain in concentrations of up to one milligram per liter.
It is appropriate to warn that both DMT and GHB are illegal drugs and their use is prohibited in many countries. So be careful when telling someone that you make these substances, even if they are. 
4 Magnetic fields
Magnetism is essential for the continuity of life. For example, the magnetic influence of the sun protects our planet from cosmic rays. And without the earth's magnetic field, solar radiation would destroy our atmosphere and kill us like ants under a magnifying glass. However, magnetic forces are not limited to celestial bodies. Life forms also create their own magnetism, and we are no exception.
Electric currents generate magnetism, so that every object in which electric currents flow also has a magnetic field. And since people are supplied with electricity that flows through our nervous system, the latter creates magnetic fields in and around our body. Each of our organs works with a certain amount of electricity, so that each part of the body has its own magnetic field.
It is estimated that the strength of the magnetic field on the surface of the human body is one ten millionth of the strength of the earth's magnetic field. The brain's magnetic field is now about 200 million times weaker than that of our planet. On the contrary, the winner among the most magnetic organs is the heart. It has a magnetic field that is only a million times smaller than Earth's magnetic force. The magnetic field of the heart is so strong that it expands outside the body and influences certain biological processes.
As you can see, the magnetic forces of the human body are very low. But that didn't stop some people from saying that they're magnetic enough to attract metal. However, little is known about the benefits of the ability to stick spoons to the body. 
This point is much more comprehensive than the rest, because not only do we have stardust in our bodies, but we are actually made of it. The idea that people are made of star materials has been around for decades, but recently we were able to prove that this is a reality.
At the beginning of the universe there were only basic elements such as hydrogen and helium. When these chemicals clustered into the first stars, heavier and more complex elements formed in these bodies. Such elements were carbon, nitrogen, oxygen, phosphorus, iron and sulfur. These elements are almost exclusively human.
How did these elements come to earth? When stars reach the end of their life, they usually explode and eject their outer layers with many different elements. After traveling long distances, the remains of these exploding stars fall to the surface of the earth, where they mix with the rest of the ground. Then plant life absorbs such elements distributed in the soil, and we eat these plants to do the same.
Over the years, the materials formed inside the stars become part of our body, which is constantly renewed with such elements. Two years ago, researchers discovered that 97 percent of the atoms in the human body are of the same type as those in stars. In addition, it is believed that 93 percent of the body mass is stardust. 
It has long been known that the human body emits light radiation. For example, the warmth of our body produces infrared light, a type of electromagnetic radiation that humans cannot see, although other animals can. When it comes to emitting visible light, one might think that this is impossible for us. Like almost all matter in the universe, we reflect light but don't emit it, do we? Well, that's not entirely true.
In 2009, a scientist at the Tohoku Institute of Technology (Japan) named Masaki Kobayashi decided to study human bioluminescence – our ability to emit light. He recruited five people and photographed their naked bodies every three hours for 20 minutes for three days. The photos were taken with extremely light-sensitive cameras. The results showed that certain parts of the individual, such as the neck and head, constantly emitted light and reached maximum brightness around four in the afternoon.
This is probably a result of our biological clock, in which we use more energy in the late afternoon. Scientists believe that our bioluminescence is generated by small molecules called fluorophores that emit photons after interacting with electrons released by cellular respiration.
But if we emit light, why don't we shine as if we were flashlights with eyes? The answer is pretty ironic: the visible light that we create is too weak to be seen. In fact, such light is a thousand times less intense than what our eyes can see. But it comes out of us every second. So they are not only made of star dust, but also shine like a star. Well, maybe not so much. 
Matter and antimatter hate each other. When these two substances collide, they destroy each other and only leave energy. But despite the volatility of antimatter in our universe, we always have some of it in us.
In order to understand how this is possible, we need to bring back potassium-40, which we previously said is human body. As already mentioned, potassium-40 is one of the radioactive isotopes or variants of potassium, a soft metal. Such isotope decays – that is, they transform into another element after their atoms lose energy. To do this, potassium-40 can be converted to calcium-40 through a process known as beta-minus decay.
During this process, a potassium 40 atom loses some particles and creates others, including an antimatter particle called Antineutrino. And this is where the math begins. It is estimated that 5,000 potassium 40 atoms decay in the human body. Around 89.25 percent of these atoms are subject to a beta-minus decay. Therefore, at least 16 million antineutrinos are formed in our body every hour.
In the meantime, potassium-40 can also be converted into the isotope argon-40. This happens when each of the potassium 40 atoms releases a positron, the antimatter version of the electron. However, this process is very rare and occurs in 0.001 percent of the cases. Taking into account the potassium 40 atoms that decay per second, the human body generates about 180 positrons per hour.
And this is the result of the conversion of only one radioactive isotope in the body. But we also have other elements that disintegrate in the same way and generate their own antiparticles at every moment. Congratulations, you are also an antimatter reactor.
