Cities have been built underground throughout history. They are typically dug underground for protection, but they may also be created as a place for living or working.

FAQ
What is the most surprising fact about your body?
There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. You're correct, there are more than 50 parts in our bodies. But, one thing is missing. A heart.
A heart is the pump that circulates blood throughout a body. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
The heart pumps about 5 liters blood per minute. This is equivalent to an adult consuming 2-3 cups of coffee per day.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. Your heart beats nearly 100 times a minute while sleeping.
The color of someone's skin can tell if they are healthy or not. The capillaries are tiny blood vessels that can be seen on the skin's surface. 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 missing in people with sickle-cell disease. They become very sick when their blood becomes hardened and sticky.
If you cut yourself, a bandage is applied to stop the bleeding. Blood must continue to flow to allow the wounds to heal properly. Doctors will insert a needle under the skin to access the vein near the injury. This allows the blood to drain from the injured area.
Doctors may also insert catheters (catheters), in an artery to treat a blood clot. This keeps patients alive until the clot has broken up naturally.
What are the darkest secrets of Hollywood?
Hollywood is full secret societies. Some are cult-like groups where members follow strict rules and rituals, while others are simply clubs for those who share common interests.
There are other nefarious entities that have a significant influence on the industry. These include the MPAA (Motion Picture Association of America), the organization that sets film ratings and RIAA(Recording Industry Association of America), the company that sets music licensing fees.
Numerous unions/guilds also represent actors and directors as well as writers, producers, and so forth. Many of the major TV networks and movie studios are owned or controlled by large corporations.
It doesn't really matter how secretive an organization may appear, there is always someone who knows exactly what they do. But that doesn't mean we should fear them.
Instead, we should embrace and celebrate them. Because they give us information that allows us to make better decisions.
These experts tell us which movies are most likely to succeed, which songs will be in demand, and what books will sell the best.
These help us to decide what we'll watch, read, listen, and buy.
We can trust them and can disregard their advice if it is not in line with our preferences.
They are more powerful than ever because we chose to ignore them. They are the supreme arbiters of taste.
They can be ignored if you don’t like what they have to say.
Let's now take a look into some lesser-known but very real Hollywood secret societies.
Observe why they are important.
How does the brain control the functions of your body?
The brain communicates with other organs to ensure their cooperation. Your body's functions are controlled by your brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. Action potentials are electrical signals that neurons send to one another. Each neuron has a cell membrane surrounding its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. Ion movement is what causes the neurons to fire.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. In turn, the second neuron also fires.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. An impulse travels along a synapse that connects the two neurons. The transmitter binds at the receptors of the post-synaptic Neuron and triggers its firing.
They are vital for the communication between nerve cells. They coordinate activity between the different parts of your brain.
What is the most secretive location in the entire world?
It may surprise you to hear the answer. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. But there is an explanation for why this place exists, and it's not what you would expect.
The City of God was its name by the ancient Greeks. In the Bible, it was known as the City of Destruction.
In India, it's called Kashi (Kashmir). It's known in Russia as Novgorod.
But here in America, it goes by another name - The Town That Disappeared.
One small community in western New York State with 1,200 residents vanished without a trace. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
The little village vanished, with no trace of its existence. Some believe the earth swallowed them up. Some claim it was destroyed by a meteorite impact. Still, others say aliens took it away.
The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They just moved to another city.
There's even a website that tracks the disappearances and recoveries of Zugspitz.
You might be wondering where this town went. It's in Switzerland.
Zugspitze is located on the border between Germany and Austria. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated and astonished me to see how many towns have vanished but still exist. Why is it that some disappear while others live on? I decided to investigate.
I wanted more information about the mysterious disappearing of towns. What causes a town to disappear? How does one place go extinct?
There are several theories behind the disappearing of towns. One theory holds that a town disappears if all its buildings are demolished. Another theory is that the town moves to another place. A third theory states that the town didn't exist at all.
The fact is that hundreds of towns all over the world have been swept away by the ground, despite theories to the contrary. This video examines both the history and current status.
