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.

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.

Fetuses with short protuberances have been observed as early as 16 weeks of gestation. While there haven't been enough studies to determine why this happens, some point to the age-old "use it or lose it" theory—the Los Angeles Times reported that periodic movements are required to keep the penile tissue oxygenated and healthy.

According to recent study from the University of Bristol, just 0.006 percent of the Korean population carries the ABCC11 gene. This gene is responsible for armpit odour. In fact, the study discovered that most East Asians lack this gene, with Koreans having the lowest amounts. While this may come as a surprise to Americans, it isn't a significant deal in Korea because deodorant isn't widely available!

According to LA Weekly, Disneyland's Clubb 33, which used to be a secret location where Walt Disney hosted important guests, is the only place in the park that serves alcohol.

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?

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!

You may or may not be aware that love can result in strong infatuation. The same serotonin levels reported in persons with obsessive-compulsive disorder, an anxiety disorder, are found in those with infatuation. This is most likely why you can't seem to think of anyone else while you're in love.

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.

When you burp on Earth, gravity keeps the solids and liquids from the food you just ate at bay, allowing only the gas to leave your mouth. Because the gas cannot separate from the liquids and particles in the absence of gravity, burping effectively becomes vomit.

If you want to do something creative, such as write a short story or design a dress, do it after a long and stressful day. This is because studies have shown that when people's brains aren't functioning as well as they should, they become more creative. This is one of the main reasons why people frequently come up with brilliant ideas while taking a shower after a long day at work.

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.

Pluto is no longer a planet, but it is still a good bet for lightening up. On the dwarf planet, a person weighing 150 pounds (68 kilogrammes) would weigh no more than 10 pounds (4.5 kg). Jupiter, on the other hand, has the most crushing gravity, weighing more than 354 pounds (160.5 kg). Mars, the planet most likely to be visited by humans, would also leave explorers dazed. Mars' gravitational pull is only 38% that of Earth's, implying that a 150-pound person would feel as if they weighed 57 pounds (26 kg). You are not fat, you are just on the wrong planet. 

Despite having one of Europe's oldest histories, Italy has only been a country since 1861. Italy was a unified entity throughout the Roman era. It was thereafter separated into independent states, which it remained until 1861. Because of this lengthy history of individualism, the country now has such a diverse spectrum of cultural variants.

During the Victorian era, there was a significant change in the way people dressed. The Victorian dress reform, also known as the rational dress movement, occurred between the 1860s and 1890s, during the middle and late Victorian eras. Reformers proposed, wore, and even designed clothing that was more practical and comfortable than what was available at the time.

There is a lot of evidence that following a pattern for 66 days will make it habitual. If you want to be better at cleaning your house or going to the gym, make a concerted effort to do so for 66 days, after which it will become a habit and be easier to maintain (this also works for breaking habits).

According to research, the average attention span has shrunk by 12 minutes in the last decade. Human attention spans are now shorter than those of goldfish. Some research has even found a link between device multitasking — such as scrolling through social media while watching TV — and declining attention spans.

In the winter, street sellers offer ice cream from paper boxes on the street. At -30 degrees Celsius, there's no need for a freezer (-22 degrees Fahrenheit).

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..

This curiosity has a social explanation rather than a scientific one. For centuries, society and the media have pushed women to hold themselves to a certain standard, whether it's small feet or a perky behind, and the majority of women have chosen stylish presentation over comfort.

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.

If you ask an American what they are, they will respond American. If you ask someone from the United Kingdom, they may claim to be British. According to The Rakyat Post, if you ask a Malaysian, they will most likely reply they are Malay, Chinese, Indian, or Dan Lain Lain, which means "other." Malaysia has a Malay population of 55%, a Chinese population of 25%, and an Indian population of 10%. There are more than 60 sub-ethnic groupings in Sarawak and Sabah alone. Malaysia is a unique melting pot of cultures, with a diverse spectrum of nationalities, and is a popular destination for travellers and expats from all over the world.

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.
