North Sentinel Island is home to one of the world's most isolated human populations. The Sentinelese, estimated to number around 300 people, have rejected all contact with the modern world and fired their arrows at anyone who comes within range. They are thought to have descended directly from the first human populations to emerge from Africa, and they have most likely lived in the Andaman Islands for up to 60,000 years.

Most of you must be thinking of SUPERCALIFRAGILISTICEXPIALIDOCIOUS as the longest word in the language that simply means ‘fantastic’ and was popularized by the movie Mary Poppins eventually added to the dictionary. But there is a longer word than this, i.e., PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS, which is the name of a type of lung disease caused by inhalation of dust and ashes. So, now try pronouncing it!

In Japan, people don’t have signatures – they have their own seal. Known as Hanko, the seal is typically your name translated into Kanji characters, and are made from silk or plant-based paste. Adults will often have three Hankos; one for signing off letters and personal matters, a bank seal and an identify seal. They’re not necessary for tourists, but foreigners living in Japan can have one handmade in small, local shops.

The Terracotta Army was discovered by chance by local farmers digging a well in 1974 in Xi'an after remaining underground for more than 2,200 years. This discovery prompted Chinese archaeologists to investigate, resulting in the discovery of China's largest archaeological site.

Yes, despite being a fictional species, the legendary unicorn is the national animal of Scotland, chosen because of its link with supremacy and chivalry and purity and innocence in Celtic mythology. BRB, I'm leaving for Scotland right now.

Plenty of Japanese celebrate Christmas, but the festive fare isn’t what you might expect. In Japan, it’s traditional to head to your local KFC on Christmas Eve. An estimated 3.6 million Japanese feast on the KFC Christmas Dinner and hours of queuing and ordering weeks in advance is expected. Some say turkey and chicken wasn’t widely available for the Christmas-curious Japanese, so Colonel Sanders stepped in to answer the demand…

Synsepalum dulcificum, also known as "Miracle Fruit," makes sour foods taste sweet when consumed. An attempt was made in the 1970s to commercialise this fruit for this purpose, but it failed. There have been allegations that the sugar industry sabotaged their research in order to avoid losing business.

The Terracotta Warriors were built between 246 BC when Qin Shi Huang assumed the Qin State throne, and 206 BC, when the Han Dynasty began, four years after Qin's death. Over 700,000 laborers worked nonstop for 40 years to complete the terracotta army and tomb complex.

When Santa Claus travels throughout the world on Christmas Eve, you may be confident that he is legally permitted to operate his sleigh—at least in the United States. The cheerful man in the red suit received his pilot's certificate from Assistant Secretary of Commerce for Aeronautics William P. MacCracken in 1927.

Almost three-quarters of adults with Internet access have at least one social media account, with 52 percent having two or more. This means that your current and potential customers are not only likely to use social media, but they are also likely to use multiple sites.

Lepioshka, or good luck bread, is a regional bread. An age-old tradition states that it should never be put upside down, since this is said to bring ill luck. Even if it's in a bag, you shouldn't leave it on the ground!

This one is a bit debatable, as some fans argue that it isn't canon. This is due to the fact that Sonic's entire name was never revealed. Archie Comics, which publishes two separate Sonic comics, published a comic in which Sonic's middle name is Maurice but his first name is never revealed. Sonic's first name is really Ogilvie, according to one of the Archie Comics authors. Fans disagree, claiming that Archie Comics' Sonic isn't actual canon, and that only the video games and Japanese comics are.

According to scientists, all of the pyramids were erected between the 26th and 23rd centuries BC. Mammoths first arose approximately 1.6 million years ago and were extinct in the 10th century BC. This indicates that when Cheops was ecstatic about a new pyramid named after him, enormous beasts were terrorizing our forefather's thousands of kilometers distant.

If you ate a Macintosh apple and planted the seed, the tree that grew would produce apples that didn't look or taste like Macintoshes. Instead of planting seeds, growers graft a cutting from a genetically desirable tree onto an existing branch or sapling (called the "rootstock"), resulting in apples that are genetically identical to those on the tree from which it was cut. If you look closely at the tree in the photo, you can see that there are several different types of apples on the various branches, all of which are grafted onto the same rootstock tree.

With a surface size of 26,300 square miles, the Aral Sea was formerly the world's fourth biggest lake. However, the lake has been rapidly diminishing since the 1960s. The lake is diminishing due to the divergence of the main rivers away from the lake for irrigation projects. As of 1997, roughly 10% of the lake had vanished, leaving only patches of smaller lakes. The majority of the south-eastern lake had already dried up by 2009, while the majority of the southwestern lake had dwindled to become a narrow strip along the old southern sea. NASA images from 2014 showed the eastern section of the old Aral Sea, which had completely dried out and is now known as the Aralkum Desert.

Among those accompanying the Queen on her journeys is usually the Queen's medical practitioner. The doctor is accountable for knowing where all local hospitals are in the cities that they visit. She also has to transport a large medical bag with a mobile defibrillator and emergency medication. Aside from that, the doctor possesses Queen Elizabeth's own blood bag, which will be used for a transfusion if necessary.

Everyone knows Lake Superior is vast (it's not called one of the Great Lakes for nothing), but few people realise precisely how big it is. Lake Superior is not only the world's biggest freshwater lake, but it also carries three quadrillion gallons of water. That's enough liquid to submerge North and South America under a foot of water. It's no surprise that Lake Superior has seen so many shipwrecks.

Speaking of heavily inhabited places, Manhattan, the most densely populated of New York City's five boroughs, has over 200 zip codes. Some buildings are even large enough to have their own elevator. The Empire State, Chrysler, and MetLife buildings are just a few examples of structures that have exclusive rights to their own unique zip code.

There are five UNESCO World Heritage sites in Uzbekistan. Itchan Kala, which boasts more than 250 historic buildings, was one of the last resting spots of caravans in the mediaeval times before crossing the desert to Iran. Itchal Kala was designated a World Heritage Site by UNESCO in 1990. Bukhara is a mediaeval city in central Asia located on the famed Silk Road, and it is said to be over 2000 years old, with various structures that are still intact. UNESCO designated the complex as a cultural World Heritage site in 1993. Other attractions in the nation include Samarkand, which is a crossroads of civilizations and was designated a UNESCO World Heritage Site in 2007.

While historians have only lately recognized their accomplishments (or female discoveries attributed to males), female mathematicians engaged in a World War II program coding instructions into the groundbreaking Electronic Numerical Integrator and Computer.

In the 1940s, Anne Frank was an iconic emblem of Nazi cruelty, while Martin Luther King, Jr. was the face and voice of the civil rights movement in the 1960s. The two events appear to be so far apart in history, although both people were born in 1929—on January 15, 1929, for King, and on June 12, 1929, for Frank. That's a mind-boggling truth, isn't it?

There are several theories as to how the phrase "it's raining cats and dogs" came to be. One example is that when houses had thatched roofs, pets and other small animals (squirrels, groundhogs, and so on) would nestle into the straw for warmth. When it rained, however, the straw became slick and the animals slid out, giving the impression that it was literally raining cats and dogs.

Even after being harvested, most fruits can still respond to their surroundings. Take, for example, the banana: A quick Google search will yield numerous methods for hastening the ripening of green bananas, as well as tips for preventing them from ripening too quickly. Avocados ripen or'soften' after being harvested as well!

Japan values good manners highly, but when it comes to chowing down on bowlfuls of noodles, there’s only one way to eat: noisily. Slurping is a sign of enjoyment and also cools down the noodles as you eat. Get your chopsticks in one hand and lean over your bowl. Bibs are sometimes provided for foreigners, but by the time you leave, you should be able to polish off a bowl in a white top and walk out spotless.
