Another fascinating Russian truth is that Russians learn not to grin as they get older. While many cultures consider smiling to be a sign of happiness and friendliness, Russians do not. Smiling, according to Russians, is a sign of weakness and not expressing one's actual sentiments. Russians grin when they see individuals they know and care about, but not when they see strangers, as many other cultures do. If you smile at a Russian on the street, don't expect them to reciprocate the favour; nevertheless, while driving around Russia, we noticed that many Russians smiled and waved back.

When it comes to the content of their dreams, researchers discovered some differences between men and women. In several studies, men reported dreaming about weapons significantly more frequently than women, while women dreamed about clothing references more frequently than men. Women have slightly longer dreams with more characters than men. When it comes to the characters that appear in dreams, men dream about other men twice as often as women, while women dream about both sexes equally.

Despite the fact that he is a fictitious character, Bruce Wayne has a higher IQ than Albert Einstein! Einstein's IQ was estimated to be between 160 and 180, while Bruce's is 192!

Scientists can detect whether a gene has been effectively inserted into an animal's DNA by adding some type of clearly recognised marker to it. When testing an anti-FIV gene in 2011, scientists at the Mayo Clinic employed a fluorescent protein from a particular jellyfish. The tests were successful, however the cats did glow in the dark. In fact, these cats' offspring sparkle in the dark! Nonetheless, their accomplishment is only one step toward an ultimate solution for AIDS.

Not everyone like frightening movies, but for those who do, there are a few hypotheses as to why, with the major one involving hormones. You receive all the adrenaline, endorphins, and dopamine from a fight-or-flight reaction when you watch a scary movie or go through a haunted house, but your brain knows that you're not truly in danger, so you get that natural high without the risk.

The mythical hero existed in real life. His given name was John Chapman, and he was from Leominster, Massachusetts. He also has a street named after him, however city planners believed that using his fabled name would be more poetic: Johnny Appleseed Lane.

There are many misconceptions surrounding Washington, but one of the most common has to do with his teeth. Washington is commonly assumed to have had wooden dentures. This is not at all the case. While Washington had severe oral issues and wore dentures, wood was never employed as a material.

According to University of California researchers, we spend 30% of our time daydreaming every day. This proportion can go as high as 70% at times (for example, during long travels), but there's nothing wrong with it. According to studies, those who enjoy floating in the clouds are more creative. They're also superior at problem-solving and stress relief.

According to the World Health Organization, only Belarus consumes more alcohol than Moldova. With each person consuming an average of 16.8 litres of liquor each year (excluding under 15s). Well that is a lot of booze..

Researchers at Arizona State University made the ground-breaking discovery that the ability to see red in all its glory is frequently gender-dependent. There is a gene that allows people to see and interpret red and its related colours such as cardinal, maroon, crimson, and so on, and that gene is linked to the x-chromosome. Because women are born with two x chromosomes, they have a better ability to see the entire red spectrum, whereas men, with a single x chromosome, aren't necessarily equipped to tell the difference between red and, say, cardinal.

Now, before you start freaking out, please hear us out! Sedentism is encouraged in today's environment. After all, we sit during our commutes, to eat, to watch TV, to work, to socialise with our friends, and so on. It turns out that even if you exercise regularly, it won't keep you safe from the risks of the "office lifestyle."

Dopamine, a neurotransmitter released during the beginning stage of a relationship, is also triggered when cocaine and nicotine are used. It provides the surge of pleasure and euphoria that makes those narcotics so addictive. It also increases the secretion of testosterone, which, as previously indicated, is necessary for attraction. If you were to choose between the three, we believe falling in love is the safer option.

A girl's brain is busy developing fine motor skills, verbal skills, and social skills in her first five years of life, all of which are highly valued by parents and teachers. Meanwhile, a boy's brain is hard at work developing gross motor, spatial, and visual skills. All of these abilities are useful for hunting. As a result, when it comes to learning and fitting in, boys frequently start school at a distinct disadvantage.

Komorebi, for example, means "sunshine flowing through leaves." It's an odd term, but if you start learning Japanese, you'll discover many more. Furthermore, the harshest curses in Japanese are "fool" and "idiot." Another fascinating aspect is slang. For example, "gaijin" means "foreigner," "baka" means "fool," and "baka-gaijin" is slang for "American."

The notion that Einstein struggled at school is a fiction. A pre-teen Einstein would study mathematics and physics for fun over the summers, finally mastering differential and integral calculus by the age of 15. But it doesn't mean he was a model student. Einstein despised rote learning and refused to study things that bore him. As a result, when the stubborn number-lover took the polytechnic school admission exam in Zurich, he flunked the language, zoology, and botany parts.

Dresses were worn by men from many cultures around the world. The Scottish kilt, for example, and the toga worn by the ancient Greeks were all examples of menswear. Dresses were only later appropriated by women, and men stopped wearing them.

Seattle residents Peter Cicero and Richard Sclafani are credited with inventing the number-themed eyeglasses that are now seen at New Year's Eve parties around the world. According to the Wall Street Journal, their first set, which read "1991," sold 500 pairs. The following year, approximately 3000 sets were purchased.

Apart from  butter-fingers, crossfire, dustbin, fairy story, slow-coach and whoosh, Charles Dickens is also credited with coining the term "boredom" in the Oxford English Dictionary, which he used in his novel Bleak House (1852-3), but this has since been traced back even further, to 1830.

Apple actually approached Verizon to collaborate in the making of the iPhone. However, Verizon had some conditions that were not liked by Apple. Thus they reached out to ‘Cingular Wireless’(AT&T Mobility)with the proposal. And, both parties agreed to all the terms and conditions and started to work on the project secretively. After working for over 2 and a half years, Apple unveiled the iPhone. The estimated development cost of the iPhone was about 150 million USD.

It's extremely unusual, yet it has happened. The event known as "coffin birth" happens when a pregnant woman dies and her kid is born spontaneously owing to gases that build up in the abdominal area, placing pressure on the mother's uterus and driving the baby through the birth pathway. According to Smithsonian, one example of this was discovered in the grave of a mediaeval woman who was buried in Italy in 2010.

Queen Elizabeth I used to use ceruse, a combination of white lead and vinegar, to paint her face. Despite how appealing these two components appear, you'll be surprised to learn that they are incredibly corrosive and ageing. "Those ladies that use it on their faces, do rapidly become withered and grey haired, for this doth so terribly dry up the naturall moisture of their flesh," one of her contemporaries observed of women who used ceruse. That sounds like a fantastic concept!

Many Koreans were forced to fight for the Japanese cause, but one soldier is said to have fought for almost everyone. According to folklore, after fighting for the Imperial Japanese Army, Korean soldier Yang Kyoungjong was captured and forced to serve for the Soviet Red Army, and then the German Wehrmacht. During this period, the Allies arrived in France, and Yang was captured by the US Army.

In the good ol' USA, around 300 billion pizzas are sold each year. Not only that, but 93 percent of Americans have eaten pizza in the last month, according to a recent survey. Around the Super Bowl, there is a significant increase in pizza delivery sales. It doesn't get any more American than that! Unfortunately, there is no official statistics on how many of those pies were devoured as a result of Amazon billionaire Jeff Bezos' "Two Pizza Rule."

Everyone has experienced the agony of rejection at some point in their lives, but did you know that rejection causes physical harm as well as emotional pain? Even if you are unable to feel physical pain, scientists have discovered that the reactions and cascading events that occur in the brain after rejection or physical pain are nearly identical. Furthermore, the same natural chemical is released in both cases.

Robin Dunbar, a psychologist and the director of Oxford University's Social and Evolutionary Neuroscience research department, believes that every guy should spend at least two hours a week with 4-5 buddies. They can use this time any way they choose, from sports to going to bars. According to Dunbar, guys with faithful friends are less likely to be sad and have a better immune system.
