Let’s take a look at how amazing - and a little freaky - our bodies are!
Messages from the human brain move at speeds of up to 200 miles per hour (322 kilometers per hour) along nerves.
The feet contain 25% of a person’s bones as an adult.
The thickest part of your skin (1.4mm) is on your feet, while the thinnest part is on your eyelids (0.2mm).
The ears and nose of a person never cease growing.
In a human mouth, there are more bacteria than there are humans on the planet.
The same skin cells that make up a human vaginal lining also make up the cells in a human mouth.
A human's DNA would span 10 billion miles from Earth to Pluto and back if it were uncoiled.
A single step can engage up to 200 muscles in an adult human.
Every ten years, a human skeleton regenerates entirely.
Bone is five times stronger than a steel bar of the same width, yet it is fragile and susceptible to fracture.
The muscles that cause the eyes to blink are the quickest in the human body. They can contract in less than a tenth of a second. A person's eyes may blink over 11,500 times in a single day.
Humans lose around 600,000 skin particles every hour, or about 1.5 pounds per year. A person will have shed roughly 105 pounds of skin by the time they are 70 years old.
An egg (or ovum) is the biggest cell in the human body and is scarcely visible to the naked eye.
Taste buds are not visible to the human eye; the little lumps on the tongue that appear to be taste buds are papillae, which sit on top of the taste buds.
Bacteria cells make up 10 times the number of human cells in your body.
The brain is made up of 86 billion nerve cells with 100 trillion connections between them. This is more than the Milky Way's total number of stars.
Each human tongue has its distinct print, similar to fingerprints.
Fingerprints will always grow back in their original pattern, no matter how badly they have been destroyed.
The excessive tendency of picking one's nose is known as rhinotillexomania.
A human sneeze may travel at speeds of up to 100 miles per hour.
The average person generates 25,000 quarts of saliva in a lifetime, enough to fill two swimming pools.
On the hand that is used to write, fingernails grow faster. They also develop more quickly than toenails, especially on longer fingers.
The masseter, or jaw muscle, is the strongest muscle in the human body.
The human brain consumes the same amount of energy as a 10-watt light bulb.
A human brain has so many nerve cells that counting them would take about 3,000 years.
The thigh bone, which is around 18 inches in length in an adult person, is the longest in the body (46 cm). The shortest bone is found in the ear, and it is about 0.1 inches (0.25 cm) long, or about the size of a grain of rice.
About 7 octillion atoms make up an adult human body.
The average individual walks around 100,000 miles (160,934 km) in their lifespan, which is equivalent to walking around the planet four times at the equator.
Daily, the normal person generates three to eight ounces of excrement.
The typical person's digestive tract contains around 5 pounds of microorganisms.
Blood flows around 12,000 miles (19,000 kilometers) every day in an adult person. It's like walking from east to west over the Pacific Ocean's largest portion.
During a lifetime, the average human heart beats approximately 3 billion times.
The brain of an adult human would be roughly the size of a pillowcase if stretched out.
In the earth's atmosphere, roughly a billion tonnes of dust is made up of dead skin.
Every 30 days, your top layer of skin (epidermis) is replaced.
A small intestine in an adult is approximately 22-23 feet long, which is roughly the length of a minivan.
About 100,000 hairs make up the typical scalp. Every year, your hair grows around 6 inches.
Every day, the average individual breaths 20,000 times.
The blood in the arteries is brilliant red, whereas the blood in the veins is black. The blood of a person is not blue.
Over 35 trillion cells make up the human body. There are 5,000 times more cells in one body than individuals globally, although Earth has roughly 7 billion people.
The medical term for nail biting is "onychophagia."
The dread of body smells is known as "bromidrophobia."
The dread of vomiting is known as "emetophobia."
Anosmia is a condition in which a person is unable to perceive scents.
Per brow, the average person has around 250 hairs. Eyebrow hairs have a four-month lifetime.
When you're hungry, your stomach creates a noise called borborygmi.
