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.

The ability to forget is a sign of high intelligence. According to scientists, forgetting is equally important as remembering. "Bad memory" is a mechanism in your brain that allows you to make more room in your brain for more relevant information. It also prevents your brain from squandering space and energy.

It's extremely unusual, yet it has happened. The event known as "coffin birth" happens when a pregnant woman dies and her kid is born spontaneously owing to gases that build up in the abdominal area, placing pressure on the mother's uterus and driving the baby through the birth pathway. According to Smithsonian, one example of this was discovered in the grave of a mediaeval woman who was buried in Italy in 2010.

Walter Arnold of the English town of Paddock Wood, Kent, was the first person to be charged for speeding, according to Guinness World Records. On January 28, 1896, Arnold was caught driving four times the speed limit in his 19th-century Benz—but because the speed limit at the time was only two miles per hour, he wasn't travelling too fast by today's standards. The officer had to track him down on his bike, issuing a £4 7s penalty and earning Arnold the swift distinction.

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.

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. 

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.

It doesn't seem to matter what others say about a new lover—in our eyes, he or she is always ideal. This blindness is essential for us to progress in our relationship. It is frequently required to progress to the "attachment stage," as scientists refer to it so that they can stay in love long enough to produce and raise children; in other words, to populate the globe.

For millions of people, the coffee break is an important but often overlooked part of their day. The town of Stoughton, Wisconsin, hosts an annual Coffee Break Festival to pause and honour the break. There will be coffee tastings, "brew-offs," and bean-spitting contests at the event. What makes Stoughton unique? According to city officials, the coffee break "was born" in the city in the late 1800s, when women working at the local Gunderson Tobacco Warehouse started the ritual of pausing during the workday to brew some coffee and chat.

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.

The date of February 14 was formally named "St. Valentine's Day" by Roman Pope Gelasius around the end of the fifth century. However, it wasn't until the Middle Ages that the festival became connected with love and passion, a tradition that sprang from the widespread belief in France and England that birds began their mating season on February 14.

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.

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, even if you're not weary, do you yawn when someone else does? There are several hypotheses as to why yawning is contagious, but one of the most popular is that it demonstrates empathy. People who are less inclined to demonstrate empathy, such as toddlers who haven't yet learned it or young people with autism, are also less likely to yawn in response to someone else's.

It may be difficult to believe, but we have roughly the same number of hairs on our bodies as chimps; the difference is that our hairs are useless, being so fine that they are almost invisible. We're not sure why we lost our furry protection. It has been proposed that this was done to help early humans sweat more easily, to make life more difficult for parasites like lice and ticks, or even because our ancestors were partially aquatic.

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.

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.

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.

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.

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.

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.

Women, believe it or not, are more vulnerable to liver disease such as hepatitis (an inflammation of the liver) and are more likely to die from liver cirrhosis (a chronic disease). Women are also more likely to suffer from alcohol-related brain damage, such as loss of mental functions and reduced brain size.

When people meet for the first time, colour recognition accounts for the vast majority of their first impressions. According to studies, those who consistently wear neutral or black make fewer positive first impressions, whereas those who wear brighter colours are more likely to form friendly bonds. Wearing hints of red (for women) or blue (for men) on a first date may result in stronger feelings and a definite second date, whereas those who wear black to a job interview are more likely to be hired.
