The blue whale is the world's largest living creature, dwarfing even the largest dinosaurs. Blue whales can grow to be over 100 feet long and weigh more than 100 tonnes. Their hearts are the size of a small car and can weigh up to 1,300 pounds. Blue whales have massive arteries that pump blood through their massive hearts and into their vital organs, which is unsurprising. These arteries are so large that a fully grown human could swim through them; however, you should not attempt this.

Any claim that chamomile will improve hair quality is speculative at best, although Kluge observes that due to its cooling and modestly anti-inflammatory characteristics, a chamomile tea hair rinse could theoretically help soothe dry and irritated scalp issues like dandruff or itching. There isn't enough scientific evidence to support its usefulness, but if you have any on hand, it can't harm to give it a shot.

The Vatican is the world's smallest nation, with an area of only 0.44 square kilometres and a population of only 825 people. It is most likely the only country in the world where you can walk around in less one hour. What makes it even more intriguing is that it is located within the city of Rome.

After the success of the 2007 film telling the story of the lovable, culinary-inspired vermin, kids everywhere asked their parents, "Can we get one? I promise I'll take care of it."

The Jewish tradition of covering up mirrors during shiva (the seven-day period of mourning by the deceased's immediate family) is still practiced today. According to several Jewish sources, when the soul departs from this world, a void is created. This void may end up attracting evil spirits to fill it. These demonic ghosts have a penchant for attaching themselves to mirror reflections. To prevent this from happening, Jews cover their mirrors until the end of shiva.

Fog is composed of tiny water droplets suspended in a cloud on the ground that contains up to 0.5 ml of water per cubic metre.

According to the CDC, approximately 7% of children between the ages of 3 and 17 years old have been diagnosed with anxiety. Since children are still developing their verbal skills they can’t say, “I have anxiety” or “I’m really worried.”
Instead, their anxiety shows up in complaints such as stomach aches, headaches, or behavioral issues like temper tantrums. Other common anxiety symptoms in children include restlessness, inattention, avoidance, and frequent meltdowns. Sadly, these symptoms often get misdiagnosed as ADHD – and then medicated.

The city got the locational advantage and it went on to become an important junction for the East India Company.

Pigeons can find their way home from 1,300 miles away, believe it or not! Furthermore, they have demonstrated that they can do so after being relocated in full isolation to a region they had never been to before. The cages were even rotated during shipment to keep the birds guessing which way they were going. Scientists aren't sure how pigeons manage to find their way back when there are no visual, olfactory, or magnetic cues to help them. They now believe that pigeons have compasses and map mechanisms that aid in navigation. While the mapping mechanism is unknown, the compass mechanism is most likely based on the location of the sun.

As you try to decide between products that treat each area of the body, the skin-care aisle at your neighbourhood drugstore might make your head spin. It's perfectly acceptable to use different products for different places depending on your preferences, skin type, and circumstances (such as acne). But keep in mind that taking care of your skin doesn't have to be difficult just because it performs a lot of tasks.

That's not to suggest the Vikings didn't have their own alphabet. They did, and they are the runes, according to popular myth. However, runes were not as widely utilized as the popular myth suggests. They were typically employed in a ritualistic manner, such as on gravestones, property marks, and identifiers for significant locations. Writing did not become ubiquitous until the Roman Catholic Church created the Roman Alphabet. It was also at this time that the famed Viking sagas transitioned from an oral tradition to being written down.

Back in the 10th century, carrots were originally white, purple, or pale yellow. So how did they get their distinct orange colour? The story goes that when William of Orange (King William III) helped the Dutch win independence from Spain in the 17th century, Dutch farmers honoured the King by turning their carrots orange through clever breeding. The new colour became hugely popular and is still the Netherlands official colour and the colour of the Dutch Royal family. The Dutch celebrate King’s Day by wearing orange and even the national sports teams wear orange.

Because the International Space Station (ISS) has Russian-language modules and operations, all astronauts who travel to the ISS must be fluent in the language. According to some astronauts, learning this new language was the most difficult aspect of their training. English-speaking astronauts can expect to spend 1,100 class hours to reach a reasonable level of fluency in Russian, according to the US State Department Foreign Service Institute. That's twice as long as it takes to learn other languages such as French, Spanish, or Dutch.

Imhotep, the world's first known physician, used Sleep Temples as healing sanctuaries. The temples were used as a type of suggestion therapy, and people would go there to be healed of physical and mental ailments. Patients who visit a Sleep Temple are said to be put under the influence of incantation or a hypnotic state. Before finally falling asleep, the physician would make whatever suggestions he could to help them overcome their problem in the hopes that the gods would visit the patient while he slept and fix them.

You may have be aware that Valentine's Day was named after its patron saint, St. Valentine — but there is some debate about which St. Valentine the celebration truly commemorates. According to History.com, at least two persons called Valentine may have inspired the festival, one of whom was a priest in third-century Rome. According to legend, this Valentine disobeyed Emperor Claudius II's marriage ban (he believed it distracted young troops), illegally married couples in the spirit of love until he was apprehended and put to death.
