Hong Kong is the eighth most densely inhabited city in the world, with 68,400 inhabitants per square mile. However, the now-demolished renowned Kowloon Walled City in Hong Kong was formerly the world's most densely populated area, with 3.2 million people per square mile! (From Wikipedia)

When Perseus took Medusa’s head, we are told that something extraordinary happened. When Medusa was raped by Poseidon, it seems that she got pregnant but for some reason, never gave birth. Consequently, when her head was removed, two children sprang from the opening. These were Chrysaor and Pegasus. Chrysaor became the father of the three-headed (or three-bodied) giant Geryon who is mainly known for his fight with Hercules. Pegasus was a winged horse and one of the most famous mythological beings. So why did Gorgon Medusa give birth to a horse? This must have to do with the fact that Poseidon was, amongst others, the god of horses.

Despite having fewer than 1,000 recognized citizens, the Vatican has the highest crime rate of any country in the world. However, this is not because it has a higher crime rate than other countries, but because it has a higher crime rate per population.

Shoplifting, purse snatching, and pickpocketing are the most prevalent crimes, and the official Vatican tourism website advises guests to remain vigilant at all times.

While she survived, such a trip is not recommended for obvious safety reasons, and individuals who try a reckless act over Niagara Falls face a hefty fine as well as the expense of rescue. Over a dozen additional individuals have gone over the falls since Taylor.

It was used for the execution of captives, including as Christians and Jews, as part of the Roman Triumph, as well as chariot racing.

Chemosensory hairs on the legs and feet detect food. Small antennae in front of their eyes are employed to track for food from a distance. "If you watch a lobster in a tank in a market, you'll notice that they're flipping about, looking for food, dissolved chemicals in the water," Bayer explains.

A fascinating part of Balinese society is that there are just four names: Wayan, Made, Nyoman, and Ketut, and people know the names of their children before they are born. The names are given in chronological sequence, therefore the first baby is Wayan, the second is Made, the third is Nyoman, and the fourth is Ketut. If there is a fifth child, they are renamed Wayan, and the cycle continues.

According to a 2011 research, Earth generates up to 40 terawatts of heat, half of which originates from radioactive decay in its core. Scientists studied antineutrinos that flowed up from Earth's core and discovered that radioactive decay of specific elements generates half of Earth's heat.

According to research, humans can only do one cognitive task at a time. Try conversing and reading at the same time or composing a letter while listening to an audiobook. Most likely, nothing positive will come of it; our brain just cannot focus on two activities simultaneously. There is, however, one exception. If the second action is entirely physical and automatic, both activities can be combined.

According to research, humans have a "satiation point" in terms of wealth when happiness peaks, and earning more would not make you happier. Various studies have indicated varying sums (one 2010 research suggested $75,000, while a 2018 poll suggested $105,000), but the conclusion is the same: Constantly pushing for more, more, more won't necessarily help you.

Seeing new individuals nude isn't as fascinating as it sounds after time. The sight of another body does not excite most OB-GYNs. "Over time, that perspective shifts from sexual to therapeutic.

"It was Krafft's astrological forecasts that led Hitler to begin the successful Operation Barossa attack," according to AstrologyCosmos.

Because of his WWII experience, he began assembling together tractors out of scrap parts when he returned home. People adored them, and his tractor company shot off like wildfire. Although they are no longer owned by the same corporation, Lamborghini Trattori is still designed by the same team that built the Gallardo and Maserati MC12. They range in price from $30,000 to more than $300,000; the only issue is whether your neighbor will still give you credit for having a Lambo.

Poveglia, Italy, is the world's most haunted island. The Romans quarantined plague patients on Poveglia Island in the 18th century.

Poveglia is off-limits to visitors, so any other creepy facts about this island will remain hidden.
