There are numerous competing theories. One idea holds that because people are more likely to drink lots of water on a hot summer day, they absorb more nutrients during the summer.

The first tea plant on the island, brought from China by the British in 1824, was showcased in the Royal Botanical Gardens near Kandy and has evolved into a big enterprise. This teardrop-shaped island nation is still a major tea producer and exporter, with more than one million of its 22 million inhabitants employed in the tea sector.

Someone born on April 20, 1889, was predicted to rise to power by an astrologer. Adolf Hitler was that "someone." Karl Krafft, a Swiss astrologer, predicted an attempted assassination of Hitler. Krafft was imprisoned by the Nazis for foreseeing the unfortunate event. When it became clear that the astrologer was not guilty, Goebbels, the Nazis' Minister of Propaganda, hired Krafft as their in-house astrologer. "It was Krafft's astrological forecasts that led Hitler to begin the successful Operation Barossa attack," according to AstrologyCosmos.

Maa Kamakhya of Guwahati is one of the oldest temples in India. There are 51 shakti peethas in different parts of India as well as in Pakistan, Nepal & Sri Lanka. The Kamakhya Shakti Peeth is considered the most powerful shakti peeth, as yoni (vagina) of Goddess Sati had fallen on the Neelanchal parvat i.e. the Nilgiri hills, following the splitting of the Goddess's dead body. Since everyone comes to this world through ‘yoni’ that is why this place is considered the center point of creating the whole Brahmand.

Although the origin of the name "Jolly Roger" is unknown, one theory attributes it to the use of red flags. A red flag was commonly used during naval warfare centuries ago to signal that no mercy would be shown and that anyone captured would be killed immediately. According to theorists, the French called it a Joli Rogue ("pretty red"), which was then translated into English as Jolly Roger. Another theory holds that the name Jolly Roger was derived from "Old Roger," a term for the Devil. Oh, these pirates are so enigmatic!

The mantis shrimp uses its two tentacles, which have the same velocity as a rifle gunshot, and dismember other shellfish by boiling the water around them to produce a shockwave that can kill animals. To put that into perspective, a human could have thrown a rock into space if they had used the same force in their arms! Additionally, the intensity of their shell is so great that it served as a model for true human body armour.

However, because executive producer Kevin Bright had previously worked with Schwimmer, the writers were already developing Ross's character in Schwimmer's voice. Schwimmer was, in fact, the first person to be cast in the show

Lower levels are almost biologically dead. One of the most intriguing aspects of the Black Sea is its absence of oxygen, which is required for life. Because oxygen can only be dissolved in the sea's top layers, anything below 230-330 feet in the centre and 330-500 feet at the edge is effectively a dead zone. Only particular bacteria can thrive in these areas, which account for more than 90% of the deeper water.

Orheiul Vechi, Moldova's most important (and possibly most beautiful) historical landmark, is a deteriorating open-air monastery complex dating back more than 2,000 years. The sprawling remains include old walls, spas, and monasteries that you will have mostly to yourself.

Most ancient Greek women were discouraged from wearing lipstick. Harlots, on the other hand, were encouraged to apply lip color in order to be clearly identifiable. In fact, the original lipstick legislation condemned harlots who appeared in public without lipstick to jail time. The Greeks believed that by wearing a bare lip, harlots might fool men into thinking they were ladies, demonstrating that even thousands of years ago, lipstick was associated with sensuality and was used as a justification to separate and subjugate women. Crocodile dung, sheep sweat, and red dye were among the materials in the Greek light paint recipe. Were they forced to use crocodile dung? Evidently, yeah.
