Some of the most fascinating facts about human bodies are surprising to learn. For example, an adult human's skeleton replaces itself every ten years. It has four blood groups and 206 bones. Two kidneys also exist. The human body is actually one of the most complex on the planet.
Every ten years, the adult human skeleton is replaced.
Throughout adulthood, the human skeleton undergoes continuous remodeling and rebuilding. Bone cell function is crucial in bone remodeling and repair. Nearly 100 percent of bone tissue in a person's body will be replaced over the course of their lives. Osteoblasts are bone cells that break down bones to make new ones. This is called bone remodeling. A bone density measurement measures the amount of bone mineral within a bone.
It has two lungs
Two lungs or lobes are located in the chest cavity. These organs exchange oxygen and remove carbon dioxide. Each lung is enclosed by a membrane called a pleura, and is connected to the heart and trachea by the main bronchus. Pleural membranes, which are thin, light and elastic, provide an air filter system. They also allow air to enter the lungs through the mouth and nose.
It has two earlobes
Despite having many similarities, human ears have different sizes, shapes, and colors. The complex system of structures within the earlobe enables us to hear and move. The average ear size for men is larger than that of women. The average ear length, at 2.5 inches, is 0.74 inches and 0.77 inch respectively. According to studies, the size of the ears grows with age.
FAQ
Why are actors blacklisted?
When you're an actor, there's more rejection than when you're a writer. You will likely be rejected many times if you are an actor. You will find someone who loves and accepts you eventually.

You might even go to auditions where you're told that you're too old, too young, or not right for the role. Or, you could lose out on a role in a movie. This happens all the time.
You may be criticised once your casting is complete. You may be told that your makeup is too heavy or you are not worthy of wearing it. If you're lucky, you won't even hear negative comments.
Sometimes your character isn't real or authentic and you will be criticised. You could be a gay actor and everyone assumes you are straight. Maybe you are a woman who is tough but cries often.
Maybe you are asked to change your vocal chords. Sometimes they ask you to sound like either a boy or a girl. They will usually ask you to sound better.
To ignore criticisms is the best way to respond. Actors feel like they've failed when told they did wrong. The truth is they haven’t done anything wrong.
They just weren't born with the talent that made them famous. Sometimes, no matter what they do, they just don't fit the bill.
Blacklisting can happen for many reasons. Some people don't like actors. Others think that actors are lazy. Others think actors are lazy.

Is there any Hollywood blacklist for actors?
There is an Hollywood blacklist.
However, the list isn’t public. As far as we know, the names aren't even known. It matters because of this.
The reason behind the secrecy was that blacklisted directors and actors wouldn't be able find work. This would result in studios losing money as the actors and directors would have to go out on their own. This would mean that they would cut back on movie production. Which would mean fewer opportunities for the blacklisted filmmakers. Which would lead them to go bankrupt.
This could eventually lead to more victims.
A contract may be required to agree to not speak against employers if someone attempts to make an Oscar winning movie. Any director or producer who would like to be nominated for an award is subject to the same rules.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Or how directors threaten to walk away from projects that don't fit their vision.
This is why Hollywood keeps a blacklist. If you speak negatively about your employer, you will likely be fired. This is bad news for anyone.
It is not uncommon for people to be falsely accused. And they've had to fight to clear their name.
This kind of thing must stop before it can happen again. It is essential that everyone has the freedom to express their opinions.
We must get rid of the Hollywood blacklist.
What is the most secretive town in the world?
You might be surprised at the answer. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. But there is a reason that this place exists. It isn't what you would expect.
The ancient Greeks called it the City of God. In the Bible, it was known as the City of Destruction.
It is called Kashi (Kashmir in India). It's also known as Novgorod in Russia.
But here in America, it goes by another name - The Town That Disappeared.
A small town in western New York State, with a population of 1,200, vanished without a trace. It was abandoned without any remains, including no bodies, cars, or houses. The only thing that survived was a road sign, which pointed to its former location.
This little town disappeared, leaving no clues about where it went or when. Some believe the earth swallowed them up. Others claim that a meteorite hit destroyed it. Still, others say aliens took it away.
Despite what may have happened, the people who lived in this once-thriving area are confident that their town will not be lost forever. They just moved to another city.
You can even track the disappearance of Zugspitz on a dedicated website.
You might be wondering where this town went. It's in Switzerland, actually!
The border of Austria and Germany is at Zugspitze. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated my that so many towns have disappeared but others still exist. Why does some vanish while others remain? I decided to investigate.
I was curious about the disappearing towns. What causes a community to disappear? How can one place become extinct?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory suggests that a community disappears when all of its buildings are removed. Another theory states that the town simply moves to another location. A third theory claims that the town never existed at all.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video explores the history of these towns and examines their current state.
Is there a more mysterious place than the Earth itself?
Antarctica is the most mysterious continent on Earth.
What is it that makes this place so interesting? Because it's unlike any other place in the world.
It is difficult to access because it is remote and extremely isolated. There is much more to this place than meets the eyes.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Some believe it refers to "land of ice". Some believe it means "land of ice". Others believe it is Greek mythology.
Antarktis was an ancient Greek name that was given to the island where Zeus and his twin brothers, Zeus. According to legend, one twin was born in winter. Thus, the term antarctic.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would signify land turned away the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the driest, windiest of all continents. It is too cold to support trees, plants, and animals.
Yet, this frozen wasteland is alive.
Here, 90 percent live of all species of living things. There are about 50% of the world's animal, plant and plant species.
What is Antarctica? Here, water freezes into ice instead of evaporating into the air.
This causes large masses to form of ice which float high above the ground.
These glaciers cover more than 80% of the continent. And they're growing larger every year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
The sea level will rise up to 200 feet if melting continues. This could lead to widespread flooding.
However, not all scientists believe this to be bad news. Some scientists suggest that global warming could actually be good for us. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.

Hollywood scandals that stunned the world
There's nothing more shocking than watching someone become famous for the wrong reasons. There's nothing more shocking than watching someone fall from grace.
The best thing about watching how an industry reacts when it makes mistakes is the best part. We've all heard about celebrities who took too much alcohol and drugs. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. That's where we found ourselves last week.
Heath Ledger gave up after a long career that was successful. After a short battle with death, Heath Ledger succumbed to prescription pills.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once thought to be one the greatest actors of all time. Two Academy Awards nominations went to Heath for his performance on Brokeback Mountain.
Heath, in addition to acting, also wrote and directed films such as A Knight's Tale (Monster's Ball) and Iron Man (3).
Hollywood loved Heath. However, he quickly grew too large. He started to use drugs and drink heavily. He ended up in rehab and became clean.
Now that he was sober, it was time to make amends. So he made a documentary called "Room 237," which chronicled the making of The Shining. It was supposed to be released this year, but now it won't hit theaters until next year.
Heath attempted to get into Hollywood every time. In fact, he was arrested twice on drug charges.
We don't believe Heath should have been allowed to go back into the entertainment industry. It would have been nice for him to have received some assistance before things spiraled outof control.
We hope Heath's story will serve as a warning to others who may think they can still have everything.
