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).

Being an astronaut is a serious profession, but they do allow for little fun every now and again. In space, "fun" activities, like as imbibing alcohol, are absolutely outlawed. However, astronauts have occasionally attempted to defy this regulation. Bottles of cognac have been "smuggled" into spacesuits by a few Russian cosmonauts. Smuggle because they couldn't lawfully transport the forbidden drug into space. They have acknowledged to mislabeling them as "juice bottles" or concealing them inside hollowed-out books. One determined astronaut concealed a little bottle in their blood pressure measurement device's wristband.

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.

You may have noticed that women take more risks than men, and there is a scientific reason for this. Women have a larger anterior cingulate cortex than men, which is the part of the brain that weighs options when making a decision. Some argue that this was evolution's way of making women better caregivers and saving the "tribe" when it came to gathering food and establishing social structures.

Archaeologists uncovered a tablet in Iraq in 1976, which has since been lost. Researchers, on the other hand, were able to interpret and decipher the writing from an image of the tablet. What were the outcomes? We know the tablet contains jokes, but the complete context has been lost in translation. The world's oldest your mother joke is "...of your mother is by the one who has relations with her." "What or who is it?" Do we comprehend it? No way, but we know a "your mom" joke when we see one!

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.

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.

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.

Unfortunately, Apple has officially announced that they will not share the iPhone sales figure anymore back on November 1, 2018. So, we actually don’t the current sales figures of the iPhone. However, we can tell you the number from 2007 to 2018, though. Reports say that Apple has sold over 2.3 billion units of iPhone in this period. And, they sold about 220 million iPhones in 2018 alone.

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.

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 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.

When kissing, 70% of individuals turn their heads to the right. A German scientist who was monitoring kissing couples in airports, train stations, and beaches came to this conclusion. Perhaps this head posture is related to being right-handed.

Tooth decay occurs when bacteria in your mouth convert sugar into acids, further eroding the tooth's surface and causing cavities. Cocoa beans contain antibacterial agents that inhibit the growth of these bacteria and help to prevent tooth decay. Dark chocolate contains more cocoa than milk chocolate. However, this does not imply that you consume chocolate on a daily basis.

We frequently get stuck in our heads with a song we don't even like. To get rid of the annoyance, simply listen to the song until the very end. This is because the so-called "earworm" is on a loop, and finishing the song helps you get rid of it.

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).

If you like crunching ice after finishing your Coke, you may be anaemic. The persistent chewing of ice, also known as "pagophagia," may be more than simply a nervous tick, but a technique of cooling inflammation in the mouth caused by a shortage of iron. So, if you enjoy nibbling on those cubes, get yourself to a doctor as soon as possible.

Curious about how Batman manages to achieve what he does? Do you want to know everything there is to know about the Dark Knight? The Science of Batman is a genuine subject offered at the University of Victoria in Canada. "The great range of flexibility of the human body explored via the life of the Caped Crusader," according to the course description.

Stubbs, an orange cat, was named honorary mayor of the Alaskan town of Talkeetna in 1997. With a population of 772 in 2000, it would not have taken many votes to win the position (and the small town didn't have a real, human mayor anyway), but Stubbs proved adept at the role, gaining fans from all over the world and "serving" in the position for years, greeting tourists and becoming a beloved symbol of the town until his death in 2017.

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.

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.

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.

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.

When explaining behaviour, we often attribute positive outcomes to internal factors and negative outcomes to external forces. When it comes to other people's actions, however, we usually attribute them to internal characteristics. For example, if we receive a poor grade on a paper, it is the fault of the teacher; if a classmate receives a poor grade, it is because he did not study diligently enough. The actor-observer bias refers to this tendency.
