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.

The most common mode of transportation for citizens in Paris is the city's subterranean rail system, which is used by over 5 million people every day.

This consumption rate of 163 litres per individual per year is unheard of in any other country in the globe. It is unsurprising that such misuse in Coca-Cola drinking may be noticed in people's health, given diabetes and obesity rates in Mexico are above normal. Other causes include a lack of exercise and an excessive intake of junk food. As a response to widespread health concerns, punitive tariffs on foods with excessive fat or sugar content were implemented in 2013.

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.

Francesco Illy, the founder of the Italian coffee roasting company, was actually born in TimiÈ™oara, Romania. He later moved to Vienna, and then the Italian city of Trieste. He didn’t make a 2006 list of the 100 Greatest Romanians, however, which was topped by Stephen the Great and featured the likes of Nadia Comăneci and Gheorghe Hagi.

Japan is made up of nearly 7,000 islands. The little island of Okunoshima in the Inland Sea is best-known for its curious, big-eared population. The island was used to test chemical weapons during World War II, and it’s said the test subjects roamed free after the war. Either way, the numbers flourished in a predator-free environment (dogs and cats are banned from entering), and today Okunoshima is a popular spot for cuddle-bunny tourists.

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.

Bananas contain potassium, which decays and makes them mildly radioactive, making them one of our weirdest scientific facts. But this is one of those amusing science facts about which you need not be concerned. According to Forbes, you’d have to consume 10,000,000 bananas all at once to die of radiation exposure.

Handshakes are only permissible between two males in Uzbekistan. A man and a woman cannot shake hands. When greeting an Uzbek woman, kneel down to her and lay your right hand over your heart.

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.

Many people believe that the Bible began as a single book, but it is actually an anthology of 66 volumes written by many authors. The first printed bible, known as the Gutenberg Bible, was published in 1455, and it was also the first book ever printed. It has been written and rewritten several times, and it has been translated into over 3000 languages during a span of around 1400 years. Furthermore, the first known text of the Old Testament dates from the 2nd century BC. There are no original manuscripts of the New Testament, but owing to fragments and early copies, researchers are very positive that the Bible we have today is more or less the same way it was first written.

Have you ever visited a salt mine? When you travel to Poland with Trafalgar, we will take you to the 800-year-old Wieliczka Salt Mine, one of the world's oldest. It's known as the Underneath Salt Cathedral of Poland, and when you go 135 metres (440 feet) underground with your guide, you'll witness chambers, sculptures, salt chandeliers, and an entire church sculpted from rock salt. The UNESCO World Heritage Site has been producing salt continuously since the 13th century until 2007, and the history and unique carvings of this salt mine will leave you speechless.

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.

Technically, it is a degree in "Viticulture and Enology" (a.k.a. grape cultivation and the science of winemaking), but we're still applying.

We still only know about a small percentage of the marine species that live in our oceans. According to the World Register of Marine Species, there are now 240,470 accepted species, but this is thought to be only a small proportion of the species that exist, as new marine life is discovered on a daily basis.

Snow White was originally drawn with big red lips, long lashes, and a shorter dress by the animators. Walt Disney, on the other hand, wanted Snow White to appear more "wholesome" (to be fair, she was 14 at the time) and chose more subdued features and a peasant-style dress.

Coffee is also one of the most addictive substances. It's a stimulant, similar to cocaine. When someone says they need a cup of coffee or that they are grouchy in the morning before coffee, they aren't joking. They might be experiencing withdrawal symptoms. Caffeine is a stimulant, which means it speeds up the transmission of signals between the brain and the body. It may be found in the seeds, nuts, and leaves of a variety of plants.

The Academy Award for Best Animated Feature normally goes to Disney or Pixar films, however during the 75th Academy Awards in 2003, the anime film Spirited Away won Best Animated Feature. However, the film's director, Hayao Miyazaki, did not attend the event due to his opposition to the Iraq war.

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…

Sure, many civilizations have their own calendars that they prefer to the Western Gregorian calendar, but the majority still obey the unwritten rule of "12 months to a year." Ethiopia is not one of them. Trying to buck the trend, Ethiopians picked up on Spinal Tap's conviction that one more is always better many thousand years ago, and have been counting 13 months to their year ever since. What exactly does this imply? Well, it's still 2009 there in 2017. And so savvy tourist boards can confidently assert that the nation has "13 months of sunlight."

China isn't bashful when it comes to banning anime for harmful content. Without hesitation, the Chinese government has outlawed famous anime series such as Highschool of the Dead, Attack on Titan, and Psycho-Pass.
