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.

Apart from  butter-fingers, crossfire, dustbin, fairy story, slow-coach and whoosh, Charles Dickens is also credited with coining the term "boredom" in the Oxford English Dictionary, which he used in his novel Bleak House (1852-3), but this has since been traced back even further, to 1830.

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.

Those enormous Stetsons you associate with cowboys like John Wayne, Billy the Kid, and Wyatt Earp? Yeah. Those were not worn by cowboys. In reality, the headgear of choice for nineteenth-century cowboys was a bowler hat.

Obviously, James Bond is a British legend, yet he is of Scottish heritage. This is particularly evident in films like Skyfall, in which Bond returns to his childhood home in Scotland. However, Bond's lineage was not revealed until later in the series. Following the popularity of Dr. No, which starred Sean Connery as the famous spy, Ian Fleming incorporated Bond's Scottish origin. Of course, Connery is Scottish. Fleming specifically included these Scottish facts in the 007 novel You Only Live Twice, eternally establishing Bond's background. Connery would subsequently feature in the cinematic version of the book, however it was hardly faithful to the source material.

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.

In the 13th century, Pope Gregory IV waged war against cats. He said that black cats were Satan's tools. He commanded the annihilation of these felines throughout Europe as a result of this notion. This strategy, however, backfired, resulting in a rise in the number of plague-carrying rats.

Ventriloquist dummies, like dolls, have become a staple of horror films. A ventriloquist's dummy named Slappy is one of R.L. Stine's most iconic antagonists. If they terrify you, avoid visiting the Ven Haven Museum near Fort Mitchell, Kentucky. Vintage ventriloquist dummies line the walls. This is undoubtedly your worst nightmare if you're afraid of dolls. How funny, these people should have destroyed them, but no, they thought why not show it to the world...

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.

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.

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.

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.

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.

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.

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.

Despite the fact that he is a fictitious character, Bruce Wayne has a higher IQ than Albert Einstein! Einstein's IQ was estimated to be between 160 and 180, while Bruce's is 192!

In the second millennium BC, ancient Egyptians described hysteria for the first time. The term 'hysteria' was coined by Hippocrates from the Greek adjective hysterikos, which means "from the womb." He blamed hysteria on the womb wandering within the female body, which caused anxiety, tremors, convulsions, paralysis, and a sense of suffocation. Hysteria was first associated with the brain in the 18th century, rather than the uterus. According to Sigmund Freud, it is caused by trauma and can affect both sexes. The DSM did not remove the concept of hysterical neurosis until 1980. Dissociative disorders are now thought to cause hysterical symptoms.

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.

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.

Danish researchers investigated 387 pairs of twins in their 70s, 80s, and 90s. They discovered that merely glancing at someone’s face may predict whether they would live until old age. If a person appears younger than their actual age, they will live longer than if they appeared older. And scientists have showed that it is pre-programmed at the DNA level. Telomeres, which are key bits of DNA that signal a cell’s reproduction ability, are also connected to how youthful a person seems. People who appear to be younger have shorter telomeres, yet longer life...

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!

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.
