The world around us in frightening facts that make us uneasy (10 photos)

People are inquisitive by nature, and therefore strive to learn something new. A huge number of educational, sometimes funny facts help us with this. But among them there are also those who make you feel uneasy.





The best description for such facts is “the less you know, the better you sleep.”

The medicine of the past, although it was effective, still has questions about it. For example, regarding how babies were operated on until the 80s. After all, doctors were convinced that babies under 15 months do not feel pain.



Because of this, they were not given anesthesia, but only a muscle relaxant to prevent them from floundering during the operation. And all because in the 40s, researchers came to the erroneous conclusion that infants did not develop the neurological abilities responsible for pain.





How did you come to this conclusion? They poked the child with a pin without getting a reaction.

There are many people who experience discomfort from traveling on the subway. However, their number may increase if you know about a study from the University of Colorado. Despite the fact that it was carried out in 2008, the trend has continued: 15% of the air in metro stations consists of dead skin from passengers.



That is, the one that is found in people, for example, in the ear canals, armpits, navel and other similar places. Needless to say, not all passengers on the subway are as clean as we would like.

Statistics can surprise, and here is another confirmation of this. Research has shown that men are much more likely to be killed on the street when meeting a stranger. In turn, for women there is even more frightening news: they are more often in danger from relatives within the walls of their home.



Surely many, while swimming in various pools, have encountered a pungent odor, attributing it to bleach. Of course, it is present in the water, but human waste helps it smell like that. When they react, they form a toxic substance, chloramine, which can cause coughing, runny nose, and, if ingested, diarrhea.



So the claims that swallowing pool water is dangerous are quite justified. By the way, chlorine, which is supposed to protect against microbes, loses its properties when in contact with urea. Therefore, if your eyes turn red after swimming, the reason for this is not chlorine, but because someone “snorted”.



The list of mental illnesses is replete with diversity. For example, there is a certain Capgras syndrome in it, when it seems that all relatives and friends have been replaced with doubles. There is also Cotard's syndrome, when a person thinks he has died. Of course, most often they indicate the development of schizophrenia, but even a very healthy person who has used psychedelic illegal substances can encounter them.



Apparently, cockroaches will forever remain in our lives and will outlive us. After all, they survived the nuclear explosions in Hiroshima and Nagasaki, which was helped by their cells, which divide many times slower than those of humans, allowing the body to eliminate the effects of radiation longer.



In addition, they can live without a head for 3 weeks, while running at speeds of up to 5 km/h. After all, their brain does not control breathing, and their blood clots well.

Well, let's end with some very sad news for left-handers. A recent study found that approximately 2,500 left-handed people die each year from using items made for right-handed people. In addition, the average lifespan of the latter is 75 years, while the former live 9 years less.



According to doctors, this is due to the fact that left-handers are more likely to face problems with the immune system and neurology.
