Speaking of astronauts, their experience has shown that transitioning from weightlessness to gravity can be taxing on the body. Muscles atrophy and bones lose bone mass in the absence of gravity. According to NASA, astronauts in space can lose 1% of their bone mass per month.

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.

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.

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.

According to the National Library of Medicine in the United States, 12% of people only dream in black and white. People under the age of 25 say they almost never dream in black and white, whereas people over the age of 55 say they dream in colour about 75% of the time.

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.

When Chaim Weizmann, Israel's first president, died in 1952, the Prime Minister invited Einstein to fill the (mostly ceremonial) office. The scientist said no, writing: "I am extremely affected by our State of Israel's offer, and I am both heartbroken and humiliated that I cannot accept it. I've spent my whole life dealing with objective issues, therefore I lack both the natural ability and the expertise to deal with people and carry out official tasks."

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."

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.

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 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.

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.

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.

Boys, more than girls, are more likely than girls to learn many lessons through experience rather than being told. This can make parenting them difficult, especially if you don't enjoy taking risks yourself. The most difficult challenge may be keeping them safe, so some risks must be avoided. It can also be difficult to be a support person as a parent when the lessons that boys learn bring hardship and tears.

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. 

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.

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!

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.

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.

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.

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 don't like grapes, wearing crimson underwear on New Year's Eve is also said to bring good luck. The custom of wearing red underwear on December 31 is widespread, spanning Italy, Spain, Bolivia, and beyond. Everyone is welcome to take part; men and women alike follow the tradition. Participants also have a variety of clothing options as an added bonus. Others wear socks, bras, and garters, while some wear red boxers, briefs, or panties.

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.

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.

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).
