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.

The "Pygmalion effect" or "Rosenthal effect" refers to the phenomenon that higher expectations can increase performance. Professor Robert Rosenthal was the first to demonstrate it. In a California elementary school, he conducted an experiment and discovered that when teachers are made aware of students who have a high chance of success, their expectations rise. As a result, they paid special attention to those students and sometimes treated them differently. Essentially, the teachers subconsciously acted differently toward those students, which promotes their success. This has a positive impact on the student, and their performance improves as a result.

First and foremost, we're not debating whether ham and pineapple belong on a pizza. Sam Panopoulos immigrated to Canada from Greece in 1954. In Chatham, Ontario, he worked as a cook at the Satellite Restaurant. Panopoulos came up with the notion of using canned pineapple on pizza in 1962. His inspiration for this unusual combo came from Chinese Sweet and Sour style food. Because of the odd fruity component, the Hawaiian pizza was first disliked. However, as people tried it, the new topping quickly became a popular option all around the world! Hawaiian pizza has nothing to do with the Hawaiian Islands. It was called after the brand of canned pineapples that they first used.

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.

There is a spa in Japan where you can bathe in coffee, as well as wine, tea, and other beverages! Bathing in coffee is said to have recharging, relaxing, and skin beautifying properties.

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."

Recently, SpaceX sent four passengers into Earth orbit aboard the Crew Dragon spaceship. A concept for an aeroplane dubbed Rukma Vimana may be found in the book Vaimanika Shastra. G. R. Josyer disclosed the book in 1952, claiming that it was authored by Pandit Subbaraya Shastry (1866–1940), who dictated it between 1918 and 1923. In 1957, the first spacecraft was launched. Looking at the images above, you can see how similar these designs are. So, how did a Pandit in India envisage the concept of a spaceship 34 years before the first spacecraft launched? Is it just a coincidence?

This occurred while he was shooting "127 Hours." According to legend, Franco enrolled in an NYU acting class where the teacher gave him a "D." He was working 127 hours at the time. Another aspect of this incident is that the professor was eventually sacked for assigning a "D" grade to Franco's paper.

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...

In another University of Pennsylvania research, one group learnt about a starving small child, another about millions dying of hunger, and a third about both conditions. People gave more than twice as much money when they heard about the little girl as when they heard the statistics—and even those who heard her tale in the context of the larger tragedy gave less. Psychologists believe that we are predisposed to help the person in front of us, but when the situation feels too vast, we believe that our small contribution is insignificant.

Your brain is working on problem solving and learning skills while you sleep. If you're learning a new skill or studying new information, getting enough sleep and having dreams can help you learn faster.

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."

Granted, everyone dislikes certain colours, but is it really possible to be afraid of a specific colour? Apparently, yes. Chromophobia, also known as Chromatophobia, is an irrational fear or aversion to certain colours. Fortunately, chromophobia is an extremely rare diagnosis that is caused by a conditioned response or a previous negative experience.

Wilbur and Orville Wright, popularly known as the Wright Brothers, are famed for inventing the aeroplane, which may lead you to assume they were a well-educated couple, however none of them graduated from college. The discovery gained the brothers fame and money, and thankfully for them, they did not live to become one of those innovators who regretted their creations.

If you're using romantic whispers to impress a potential partner, make sure to speak into his or her left ear. An MITCogNet study discovered that when emotion stimuli were delivered to the left ear, recall accuracy was more than 6% higher than when the same stimuli were delivered to the right ear.

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.

A translator rewrote the story in the 1600s. When the prince attempted to follow Cinderella, Aschenputtel (Cinderella) lost her left shoe at the stairwell.

Scientists from the University of Birmingham investigated bikers aged 55 to 79 who ride their bikes for many hours each day. These researchers discovered that cycling in old age keeps muscle mass and strength from deteriorating. And the fat and cholesterol levels remained constant. However, the most incredible discovery is that cyclists' systems generate immunological T-cells in equal numbers to 20-year-olds. It's incredible since T-cell production begins to decline around the age of 20. This demonstrates that riding a bicycle makes the immune system younger.

The amount of bourbon barrels in Kentucky outnumbers the state's population by more than two million. That's quite a bit of bourbon. Kentucky is the home of bourbon and produces 95 percent of the world's supply.

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.

Obviously, James Bond is a British legend, yet he is of Scottish heritage. This is particularly evident in films like Skyfall, in which Bond returns to his childhood home in Scotland. However, Bond's lineage was not revealed until later in the series. Following the popularity of Dr. No, which starred Sean Connery as the famous spy, Ian Fleming incorporated Bond's Scottish origin. Of course, Connery is Scottish. Fleming specifically included these Scottish facts in the 007 novel You Only Live Twice, eternally establishing Bond's background. Connery would subsequently feature in the cinematic version of the book, however it was hardly faithful to the source material.

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.

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.
