If you're familiar with Spider-Man, you'll know that one of his most potent talents is his renowned Spider Sense. This heightened sense had alerted him of impending threats and had saved his life several times. His spidey sense was always on and practically hard to avoid. It was unaffected by darkness or blindness. That alone makes it incredible, but it is far more potent than you may expect. It alerted him of existential hazards to his well-being in addition to acute bodily concerns. It would even warn him to any possible witnesses when he changed his outfit, for example.

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.

John Duns Scotus, a thirteenth-century philosopher, believed that wearing a pointed cap would help spread knowledge from the tip to the brain, and his "Dunsmen" followers wore them as a badge of honour. However, his ideas became less popular in the 1500s, and the meaning of the Duns cap was turned on its head, becoming something of a joke.

During the first year of being in a romance, a protein in our cells called Nerve Growth Factor (NGF) that is vital for the functions of particular sympathetic and sensory nerve cells, appears to thrive. During youthful love, our senses are heightened, and our fight or flight reaction system is activated.

Russians are divided on this truth regarding Poland, however it is widely assumed that vodka was developed in Poland. The spirit was first mentioned in recorded form in Polish court papers in 1405, and it was first utilised as medication.

Katie Mulcahey, a New Yorker, was jailed in 1908 for striking a match on a wall and lighting a cigarette with it. Why? Because it was a breach of The Sullivan Ordinance, a local ordinance that prohibits women (and only women!) from smoking in public. Mulcahey protested for her right to smoke cigarettes in public at her hearing in district court. She received a $5.00 fine. The Sullivan Ordinance was vetoed by New York City's mayor two weeks later.

Ancient Egyptians regarded cats to be sacred creatures. Most households are said to have kept a cat as a pet because they felt it would bring them good luck!

According to research, our brain can only keep 3-4 pieces of information at a time. Furthermore, this data can only be saved for 20-30 seconds. We forget it after this period unless we keep renewing it in our minds over and again. For example, you are driving while chatting on the phone (do not do this!). The person on the other end of the line gives you a number, but you can't write it down, so you memorize it. You repeat the number several times to keep it in your short-term memory until you disconnect and write it down.

To obey authority figures, people will go to great, and sometimes dangerous, lengths. Stanley Milgram, a psychologist, discovered in his famous obedience experiments that people would be willing to deliver a potentially fatal electrical shock to another person if the experimenters ordered them to.

Why doesn't your stomach digest itself if it has so many enzymes and acids that it can digest a piece of meat? It turns out that it sort of does. The cells that line your stomach proliferate fast in order to replace the cells that are killed in the course of their everyday tasks. Every three days, we develop a new gut lining.

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.

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.

According to World Tourism Organization statistics, Mexico has the greatest number of international tourists in Latin America and is rated #10 in the world. This is unsurprising considering the variety of culture and environment on offer in Mexico. UNESCO has designated 32 places in the nation as World Cultural Heritage sites. Mexico tops the American continent in this area once more, and is ranked sixth overall.

Another fascinating truth about Russia is that Russians, in general, have a lot of superstitions and customs. One of the most prevalent customs is to gift flowers only in odd numbers. Many Russians think that an odd amount of flowers should only be used in graves. If you gift an even amount of flowers to a Russian, they will take it personally. In addition to not giving away an even amount of flowers, Russians believe that clothing should not be worn inside out. The Russians think that if you put your clothing on inside out, you will be defeated.

In the second millennium BC, ancient Egyptians described hysteria for the first time. The term 'hysteria' was coined by Hippocrates from the Greek adjective hysterikos, which means "from the womb." He blamed hysteria on the womb wandering within the female body, which caused anxiety, tremors, convulsions, paralysis, and a sense of suffocation. Hysteria was first associated with the brain in the 18th century, rather than the uterus. According to Sigmund Freud, it is caused by trauma and can affect both sexes. The DSM did not remove the concept of hysterical neurosis until 1980. Dissociative disorders are now thought to cause hysterical symptoms.

Official statistics show that over half of all persons up to the age of 64 have the equivalent of a high school graduation, significantly below the OECD average of nearly 75%. Younger generations, on the other hand, are defying the trend, with 65 percent of millennials obtaining the certificate — and the number is climbing.

We frequently predict how we will react to a future event, only to find out that we reacted completely differently than we anticipated. We put our faith in the ability of a single event to change everything, but we frequently discover that it has little effect on how we feel.

Though concluding definitively that colour affects a person's psyche has proven difficult, there have been a plethora of studies — some official, some not so official — that have come close. These investigations date back to the 1930s, when neurologist Kurt Goldstein began experimenting with colour and appearance. Goldstein discovered, for example, that people automatically assume red objects are heavier, while green objects are lighter.

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.

Men have selective hearing, it's a fact! They can only listen to their female partners for 6 minutes, but this time is more than doubled to 15 minutes when they talk to their male friends. Before you start blaming men for their lack of attention, keep in mind that women pay more attention to conversations with their friends than to conversations with their romantic partners.

The Egyptians placed a high value on the afterlife. They thought that by mummifying a deceased person's corpse, their spirit would continue on in the afterlife for all eternity.

Ventriloquist dummies, like dolls, have become a staple of horror films. A ventriloquist's dummy named Slappy is one of R.L. Stine's most iconic antagonists. If they terrify you, avoid visiting the Ven Haven Museum near Fort Mitchell, Kentucky. Vintage ventriloquist dummies line the walls. This is undoubtedly your worst nightmare if you're afraid of dolls. How funny, these people should have destroyed them, but no, they thought why not show it to the world...

Cheese rolling is one of the oddest sports that takes place every spring in Gloucestershire, in the west of England. An 8-pound round of Double Gloucester cheese is rolled from the top of Cooper Hill, and competitors pursue it down to the bottom. They are intended to catch the cheese, but it is nearly impossible, thus the first person to cross the finish line wins the cheese.

Italy was a dictatorship until 1945, while having a royal dynasty until 1946. Following WWII, the country decided to become a republic, and King Umberto II governed briefly from May 9 to June 12, 1946. He spent the rest of his days in exile in Portugal. In Italy, he is regarded as "the May King," a reference to his exceptionally brief rule.
