Throughout the ages, cities have been built underground. They are typically dug underground for protection, but they may also be created as a place for living or working. Underground cities are a concept that dates back to Ancient Era Europe, the Middle East and other places. They could have been built as a defense refuge, mausolea, storage cellars or storage tanks. They may also serve as transport, especially in cold climates.
Underground cities are networks of subterranean spaces linked by skyways or underground tunnels. They can be used to transport or provide access to shops, restaurants, or other activities. They could also be used for storage and defense against natural catastrophes. Some underground cities can be accessed by the public while others are restricted to certain passageways.

Why do actors end up on the blacklist?
Actors are more likely to be rejected than writers. An actor will probably be rejected quite often. It doesn't matter, because you will eventually find someone you love.
Actors have a lot of talent, so they can make a decent living almost anywhere. Actors don't really care about making money. Actors love to act and tell stories. You'll be an actor if you love acting.
It is possible to be told that you are not suitable for the role, or that you are too old or too young. Or you might audition for a movie and lose out to another person. This happens all the time.
You may be criticised once your casting is complete. Some people will say that you look awful or shouldn't wear makeup. If you're lucky, you won't even hear negative comments.
Sometimes, you might be criticised for playing a role that isn’t authentic or realistic. Perhaps you play a homosexual man and everyone thinks that you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Sometimes, they ask you to change your voice. Sometimes, they will ask you to sound more like a woman or a man. They will usually ask you to sound better.
These criticisms should be ignored. Actors often feel like they've failed if they're told they did something wrong. However, they aren't doing anything wrong.

Is there a more mysterious place than the Earth itself?
Antarctica is one of the most mysterious places on Earth.
We find this place so fascinating. Because it's unlike any other place in the world.
It is isolated, remote, and very hard to visit. It is not what you see.
Some of the most bizarre wildlife species can also be found in this natural wonder.
So let's explore how this remarkable destination became famous for its mystery.
Antarctica, The South Pole
Antarctica is not known by anyone. Some say it means "land on ice." Some believe it means "land of ice". Others believe it is Greek mythology.
Antarktis in ancient Greece was the name given the island where Zeus' twin brother brothers were born. According to legend, one twin was born in winter. Hence, the word antarctic.
Others believe that the name is a combination of the Greek words anti and tropos which mean against and turn. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the coldest, windiest, driest and highest continent. It is too cold for trees, plants and animals.
Yet, this frozen wasteland is alive.
Here are about 90% of all the living creatures on Earth. Here are approximately 50% of all the animal and plant species in the world.
What makes Antarctica so special? Here, water freezes in ice rather that vaporizing into the atmosphere.
This creates large masses of ice that float above the ground.
These floating glaciers cover over 80%. And they're growing larger every year.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting continues, the sea level will rise by up to 200 feet. This could lead to widespread flooding.
This does not mean that everyone is wrong. Some scientists believe that global warming can be beneficial. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
What is the most interesting fact about the human body?
We have two eyes, two ears, two nostrils, four limbs, a mouth, a nose, and a penis. That's right, we have more than 50 parts of our bodies, but one thing is missing. A heart.
The heart is a pump that circulates blood throughout your body. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
Each minute, the heart pumps 5 liters of blood. This is equivalent to a person drinking 2-3 cups coffee daily.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. Your heart beats nearly 100 times a minute while sleeping.
Because of the color and texture of their skin, you can tell if someone is healthy or sick. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These vessels carry blood away to the heart via the large blood vessels. The skin becomes blue-colored or purple when blood flow is restricted.
Red blood cells are not available to sickle cell patients. Patients with sickle cell disease have their blood become sticky and harden, leading to severe illness.
To stop bleeding from a cut, you can apply a bandage to the wound. Blood must flow in order for the wound to heal properly. Doctors will insert a needle under the skin to access the vein near the injury. This allows the blood from the injured area to drain.
Doctors also insert tubes (catheters) into the artery near the site where the blood clot forms. This keeps patients alive until the clot has broken up naturally.
Statistics
