You might have already noticed that every picture of iPhones on any advertisement has the time set at 9:41. But why is that? There is a cool story behind this. When Steve Jobs announced the first iPhone, the local time was 9:42 at that time in San Francisco, California. They knew that they will unveil the iPhone at 9:42 and set the time to 9:42 in the slideshow as well.

However, when the iPad was released, they announced it at 9:41. Since then, this is still in effect as of yet. So, whenever you see an iPhone in any advertisement, you will see the time is set at 9:41. And, it is not a coincidence at all. Now you know the story behind this as well.

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.

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.

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."

A translator rewrote the story in the 1600s. When the prince attempted to follow Cinderella, Aschenputtel (Cinderella) lost her left shoe at the stairwell.

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.

You may have outgrown the hours-of-making-out-on-the-couch stage of your relationship, but you shouldn't dismiss kissing as a pleasurable pastime with your partner—and also a type of exercise!

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.

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.

Though some historians think that Valentine's Day commemorates St. Valentine's death on February 14, others believe that the event derives from a Pagan fertility festival known as "Lupercalia," which was held on February 15 in ancient Rome. The day was dedicated to Faunus, the Roman god of agriculture, and the Roman founders Romulus and Remus, and was celebrated by sacrificing animals and slapping women with animal skins, a technique thought to increase fertility.

Martin Lotze, a German researcher, studied the brains of both professional athletes and professional writers and discovered that their brain activity during athletic competition and the writing process was very similar. Lotze discovered an interesting difference between professional and amateur writers: professional writers used their speech-processing centres of the brain to develop their stories, whereas amateur writers relied on their vision centres to imagine the story first.

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.

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.

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!

A girl's brain is busy developing fine motor skills, verbal skills, and social skills in her first five years of life, all of which are highly valued by parents and teachers. Meanwhile, a boy's brain is hard at work developing gross motor, spatial, and visual skills. All of these abilities are useful for hunting. As a result, when it comes to learning and fitting in, boys frequently start school at a distinct disadvantage.

Austrians celebrated their victory over Hungary during the 1848 revolution by clinking their drinks during a toast. Since then, Hungarians have avoided clinking their glasses while toasting since it reminds them of their loss.
