Human Facts

Stomach lining cells produce mucus, pepsin, HCl to a pH of 2.0 (100,000X the acidity of your bloodstream)

More than half the bones in the human body are in the hands and feet.

The highest recorded "sneeze speed" is 165 km (102 miles) per hour.

The heart beats about 3 billion times in the average person's lifetime.

A newborn baby has 350 bones, but a fully-grown adult has only 206.

Blood is a liquid organ.

Everyone is colorblind at birth.

Our lungs inhale over two million liters of air every day, without even thinking. The surface area of the lungs is approximately the same size as a tennis court.

Food will get to your stomach even if you're standing on your head.

Skin is the largest body organ.

The average adult is made up of 100 trillion cells.

There are more bacteria in your body than the number of cells in your body. There are an estimated 75 to 100 trillion cells in the human body.

Our brain is more complex than the most powerful computer and has over 100 billion nerve cells.

Capillaries are so small that red blood cells can only travel through them in single file.

The cornea, the outermost layer of the eye, is the only living tissue in the human body without blood vessels? It receives nutrients from tears and from the aqueous humor.

Each cell in your body has an estimated 6 to 8 feet of DNA.

Research has shown that guilt damages your immune system by lowering your immunoglobulin levels.

The total length of your circulatory system stretches an amazing 60,000 miles. That is more than twice the distance around the Earth.

In one square inch of skin there are four yards of nerve fibers, 600 pain sensors, 1300 nerve cells, 9000 nerve endings, 36 heat sensors, 75 pressure sensors, 100 sweat glands, 3 million cells, and 3 yards of blood vessels.

Except for your brain cells, 50,000,000 of the cells in your body will have died and been replaced with others, all while you have been reading this sentence.

Your heart beats about 100,000 times in one day and about 40,000,000 times a year. In one hour the heart works hard enough to produce enough energy to raise almost one ton of weight one yard from the ground.

The liver is often called the body's chemical factory. Scientists have counted over 500 liver functions.

The central nervous system is connected to every part of the body by 43 pairs of nerves. Twelve pairs go to and from the brain, with 31 pairs going from the spinal cord. There are nearly 45 miles of nerves running through our bodies.

Messages travel along the nerves as electrical impulses. They travel at speeds up to 248 mile per hour.

The central nervous system is the master system of all functions within your body and has a reciprocal Neurophysiologic relationship with the Acupressure Meridian and Chakra (Emotional Energy Centers) Systems of energetic function within your being. Subluxations in your spine, cranium and extremities, interfere with the flow of nerve impulse energy information and acupressure meridian energy within your body.

The aorta, the largest artery in the body, is almost the diameter of a garden hose. Capillaries, on the other hand, are so small that it takes ten of them to equal the thickness of a human hair.

Your body has about 5.6 liters (6 quarts) of blood. These 5.6 liters of blood circulates through the body three times every minute. In one day, the blood travels a total of 19,000 km (12,000 miles) - that's four times the distance across the US from coast to coast.

Our eyes can distinguish up to one million color surfaces and take in more information than the largest telescope known to man.

Our hearing is so sensitive it can distinguish between hundreds of thousands of different sounds.

Our sense of touch is more refined than any device ever created.

We give birth to 100 billion red blood cells every day and about two million red blood cells every second.

When we touch something, we send a message to our brain at 124 mph.

We have over 600 muscles.

We exercise at least 30 muscles when we smile.

We are about 70 percent water.

We make one liter of saliva a day.

Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities.

We have copper, zinc, cobalt, calcium, manganese, phosphates, nickel and silicon in our bodies.

If you yelled for 8 years, 7 months and 6 days you would have produced enough sound energy to heat one cup of coffee.

During the first month of life, the number of connections or synapses, dramatically increases from 50 trillion to 1 quadrillion. If an infant's body grew at a comparable rate, his weight would increase from 8.5 pounds at birth to 170 pounds at one month old.

The average life of a taste bud is 10 days.

Margarine is but ONE MOLECULE away from being PLASTIC...

Our bodies contain enough water to fill a ten-gallon tank.

We have enough carbon to manufacture 900 pencils.

Fingernails are one of the human body's strongest components. They contain keratin, which is also found in rhino horns, which refuses to erode after death.

Babies are not fully naked in the womb. In fact, their entire bodies are usually covered in a thin layer of dark hair by the end of the fifth month of pregnancy, which disappear when the baby is born.

People blink once every four seconds. That's because the eyelashes act as windscreen wipers, keeping dust and grime from getting into the eye itself.

Humans are one of the only mammals who are unable to 'turn' their ears in order to hear approaching predators.

An embryo is genderless for the first 6-8 weeks of pregnancy. Only after that the body decides whether the baby will be a boy or girl through dominant hormones that emerge.

Every tongue has its own individual print, which is unique to each person.

The big toe is actually one of the most important elements within the body, as it balances the skeleton and enables the owner to move forward when walking without it, we would simply fall over.

If the population of China walked by you in single file the line would never end because of the rate of reproduction.

If a person has two-thirds of their liver removed from trauma or surgery, it will grow back to its original size in four weeks time.

On average, you breathe 23,000 times a day. You take about 600 million breaths during your lifetime.

A person can live without food for about 40 days, but only about 7 days without water, 6-8 minutes without air, and literally an instant without Life Force.

Among the top ten causes of death in the US are toxic reactions to correctly prescribed drugs, which make more than two million Americans seriously ill every year, and kill 106,000 more. Incorrectly prescribed drugs account for another 90,000 deaths each year!

The odds of being struck by lightning are about 600,000 to one.

It is normal to lose 100 hairs per day from the scalp.

We take about 600 million breaths during our lifetime.

There are more bacteria in your mouth than the human population of US and Canada combined.

There are more than 1,000 chemicals in a cup of coffee. Of these, only 26 have been tested, and half caused cancer in rats.

The average human body contains enough: Sulfur to kill all fleas on an average dog, Carbon to make 900 pencils, Potassium to fire toy cannon, Fat to make 7 bars of soap, Phosphorus to make 2,200 match heads, and enough water to fill a ten gallon tank.

If you could save all the times your eyes blink in one lifetime and use them all at once you would see blackness for 1.2 years!

Fact: In one square inch of skin there are four yards of nerve fibers, 1300 nerve cells, 100 sweat glands, 3 million cells, and 3 yards of blood vessels.

Fact: Except for your brain cells, 50,000,000 of the cells in your body will have died and been replaced with others, all while you have been reading this sentence.

Fact: The adult heart beats about 40,000,000 times a year. In one hour the heart works hard enough to produce enough energy to raise almost one ton of weight one yard from the ground.

Fact: The liver is often called the body's chemical factory. Scientists have counted over 500 liver functions.

Fact: The central nervous system is connected to every part of the body by 43 pairs of nerves. Twelve pairs go to and from the brain, with 31 pairs going from the spinal cord. There are nearly 45 miles of nerves running through our bodies.

      The Hindu Yoga practicioners have estimated that the faster you breath, the sooner you die. In fact, Dogs live on average 13 to 14 years. They breath about 30 times a minute. Turtles breathe 7 to 8 times a minute and live far over 100 years. These are general speeds, and it varies such as physical activity. Birds and mosquitoes die much faster. Their metabolism is much higher and the smaller animals are 'far' faster than any human. Turtles are 'very' slow.

      15 My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.

      16 Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them.

      17 How precious also are thy thoughts unto me, O God! how great is the sum of them!

      In response to your comment, the site did express some math in regards to the average times a person breaths each year. "On average, you breathe 23,000 times a day. You take about 600 million breaths during your lifetime." Those numbers crunch down to 8,386,560 a year, 23,040 times a day, 960 times an hour, and 16 times a minute. The 600 million breaths a life time is based on a 71 year 5 month 4 day life span! Of course these are all rough figures considering the breath per second ratio can vary heavily between active and non active times, age, gender, weight, body size, and physical fitness. So in light of that, enjoy!
