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.

Everyone has experienced the agony of rejection at some point in their lives, but did you know that rejection causes physical harm as well as emotional pain? Even if you are unable to feel physical pain, scientists have discovered that the reactions and cascading events that occur in the brain after rejection or physical pain are nearly identical. Furthermore, the same natural chemical is released in both cases.

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.

In Italy, he is regarded as "the May King," a reference to his exceptionally brief rule.

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."

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.

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.

Seattle residents Peter Cicero and Richard Sclafani are credited with inventing the number-themed eyeglasses that are now seen at New Year's Eve parties around the world.

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.

And, they sold about 220 million iPhones in 2018 alone.

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 University of California researchers, we spend 30% of our time daydreaming every day. This proportion can go as high as 70% at times (for example, during long travels), but there's nothing wrong with it. According to studies, those who enjoy floating in the clouds are more creative. They're also superior at problem-solving and stress relief.

According to a neurologist research, some individuals who have had brain trauma and have acquired damage on the right side of their brain have an obsessive preoccupation with making jokes that they deem humorous while not finding other people's jokes funny.

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.

There was a long-held belief that a sneeze travels at 100 mph, but current study has revealed that this is not the case. Nonetheless, that achoo is rather amazing. According to a 2013 research published in PLOS One, a sneeze moves at a pace of around 10 mph. Nonetheless, cover your mouth and nose to protect others from germs.

Einstein was leaving a ceremony in his honour on his 72nd birthday. Photographers begged him to grin for the camera as he was getting into his car. Einstein, on the other hand, was weary of smiling for photos—he'd be doing it all evening—so he stuck his tongue out instead. Einstein was so taken with the photograph that he had it printed as greeting cards.

People who have a full bladder are more convincing liars. A strong urge to use the restroom causes a person to focus on self-control, making lying more plausible. Furthermore, they attempt to prevent unnecessary movement. That's why scientists conducting a scientific experiment believed liars who needed to go to the bathroom.

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.

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.

On Mondays, the chance of suffering a heart attack rises by 20% for men and 15% for women. It's most likely due to the stress of having to return to work. However, scientists caution that alcohol drank over the weekend can potentially be a cause of a heart attack.
