Over the next few days I will post some amazing facts that most of us do not know.
Today I will start with - The human body
Hiccups happen when the diaphragm, the muscle that controls our breathing, becomes irritated and start to spasm and contract uncontrollably. With each contraction, air is pulled into the lungs very quickly, passes through the voice box, and then the epiglottis closes behind the rush of air, shaking the vocal chords, causing the "hic" sound. The irritation can be caused by rapid eating, emotional stress and even some diseases. The best cure? Breathing into a paper bag. This calms the diaphragm by increasing the amount of carbon dioxide in your bloodstream.
The length from your wrist to your elbow is the same as the length of your foot.
Your heart beats 101,000 times a day. During your lifetime it will beat about 3 billion times and pump about 400 million litres (800 million pints) of blood.
Your mouth produces 1 litre (1.8 pints) of saliva a day.
On average, people can hold their breath for about one minute. The world record is 15 minutes 2 seconds, by Tom Sietas..
The human head contains 22 bones.
On average, you breathe 23,000 times a day.
On average, you speak almost 5,000 words a day - although almost 80% of speaking is self-talk (talking to yourself).
Einstein's brain was of average size (1375 grams - 49oz).
Over the last 150 years the average height of people in industrialised nations increased by 10 cm (4 in).
In the 19th century, American men were the tallest in the world, averaging 1,71m (5'6"). Today, the average height for American men is 1,75m (5'7"), compared to 1,77m (5'8") for Swedes, and 1,78m (5'8.5") for the Dutch.
The tallest nation in the world is the Watusis of Burundi.
If the amount of water in your body is reduced by just 1%, you'll feel thirsty.
Hippocrates, the Father of Medicine, suggested that a woman could enlarge her bust line by singing loudly and often.
A person can live without food for about a month, but only about a week without water.
You'll drink about 75,000 litres (20,000 gallons) of water in your lifetime.
After a certain period of growth, hair becomes dormant. That means that it is attached to the hair follicle until replaced by new hair.
Hair on the head grows for between two and six years before being replaced. In the case of baldness, the dormant hair was not replaced with new hair.
Men loose about 40 hairs a day. Women loose about 70 hairs a day.
In the Middle Ages the length from the tip of the middle finger to the elbow was called an ell.
A person remains conscious for eight seconds after being decapitated.
The first human sex change took place in 1950 when Danish doctor Christian Hamburger operated on New Yorker George Jargensen, who became Christine Jargensen.
The muscle that lets your eye blink is the fastest muscle in your body. It allows you to blink 5 times a second. On average, you blink 15 000 times a day. Women blink twice as much as men.
A typical athlete's heart churns out 25 to 30 litres (up to 8 gallons) of blood per minute.
We have four basic tastes. The salt and sweet taste buds are at the tip of the tongue, bitter at the base, and sour along the sides.
Unless food is mixed with saliva you cannot taste it.
The liver is the largest of the body's internal organs. The skin is the body's largest organ.
Not all our taste buds are on our tongue; about 10% are on the palette and the cheeks.
On average a hiccup lasts 5 minutes.
Fingernails grow nearly 4 times faster than toenails.
It takes about 3 months for the transplanted hair to start growing again.
About 13% of people are left-handed. Up from 11% in the past.
In 1900, a person could expect to live to be 47. Today, the average life expectancy for men and women in developed countries is longer than 70 years.
A newborn baby's head accounts for one-quarter of its weight.
King Henry I, who ruled in the England in the 12th century, standardised the yard as the distance from the thumb of his outstretched arm to his nose.
The bones in your body are not white - they range in colour from beige to light brown. The bones you see in museums are white because they have been boiled and cleaned.
Our eyes are always the same size from birth.
Every person has a unique tongue print.
If all your DNA is stretched out, it would reach to the moon 6,000 times.
Approximately two-thirds of a person's body weight is water. Blood is 92% water. The brain is 75% water and muscles are 75% water.
The coloured part of the eye is called the iris. Behind the iris is the soft, rubbery lens which focuses the light on to a layer, called the retina, in the back of the eye. The retina contains about 125 million rods and 7 million cones. The rods pick up shades of grey and help us see in dim light. The cones work best in bright light to pick up colours.
We actually do not see with our eyes - we see with our brains. The eyes basically are the cameras of the brain. One-quarter of the brain is used to control the eyes

Todays facts- Animals
Is a world population of 6 billion too many? Compare that with animals. There are more than a million animal species. There are 6,000 species of reptiles, 73,000 kinds of spiders, and 3,000 types of lice. For each person there is about 200 million insects. The 4,600 kinds of mammals represent a mere 0,3% of animals and the 9000 kinds of birds only 0,7%. The most numerous bird specie is the red-billed quelea of southern Africa. There are an estimated 100 trillion of them.
Mammals are the only animals with flaps around the ears.
African elephants only have four teeth to chew their food with.
There are about one billion cattle in the world of which 200 million are in India.
A house fly lives only 14 days.
A dog was the first in space and a sheep, a duck and a rooster the first to fly in a hot air balloon.
The Big Five is a group of animals of Africa: cape buffalo, elephant, leopard, lion and rhino. The term "Big Five" was coined by hunters who referred to the difficulty in hunting these wild animals because of their ferocity when cornered.
The oldest breed of dog is the Saluki.
The bee hummingbird of Cuba is the smallest bird in the world.
An ostrich can run up to 70 km/h (43mph).
An annoyed camel will spit at a person.
The world's smallest dog is the Chihuahua, which means "tiny dog in the sky."
Pea crabs (the size of a pea) are the smallest crabs in the world.
75% of wild birds die before they are 6 months old.
The pig is rated the fourth most intelligent animal but are mentioned only twice in the Bible
Sheep are mentioned 45 times and goats 88 times in the Bible. Dogs are mentioned 14 times and lions 89 times, but domestic cats are not mentioned.
Pork is the world's most widely-eaten meat.
In Denmark there are twice as many pigs as people.
Dinosaurs did not eat grass: there weren't any at that time.
The coyote is a member of the dog family and its scientific name, "canis latrans" means barking dog.
A giraffe can clean its ears with its 50cm (20 in) tongue.
A group of geese on the ground is a gaggle - a group of geese in the air is a skein.
More animal collective nouns
The South American giant anteater eats more than 30,000 ants a day.
It is impossible to out-swim a shark - sharks reach speeds of 70 km/h (44 mph). Humans can run about 35 km/h (21 mph).
The sailfish is the fastest swimmer, reaching 109 km/h (68 mph).
The slowest fish is the Sea Horse, which moves along at about 0.016 km/h (0.01 mph).
Dolphins can reach 60 km/h (37 mph).
Of the 650 types of leeches, only the Hirudo medicinalis is used for medical treatments.
The heart of a blue whale is the size of a small car.
The tongue of a blue whale is as long as an elephant.
The scales of a crocodile are made of ceratin, the same substance that hooves and fingernails are made of.
A crocodile's tongue is attached to the roof of its mouth and cannot move it.
A snail has two pairs of tentacles on its head. One pair is longer than the other and houses the eyes. The shorter pair is used for smelling and feeling its way around.
The heaviest crustacean ever found was a lobster weighing 19 kg (42 lb), caught in 1934.
The largest jellyfish ever caught measured 2,3 m (7'6") across the bell with a tentacle of 36 m (120 ft) long.
The largest giant squid ever recorded was captured in the North Atlantic in 1878. It weighed 4 tons. Its tentacles measured 10 m (35 ft) long.
The giant squid has the biggest eyes of any animal: its eyes measure 40 cm (16 in) in diameter.
Domestic cats purr at about 26 cycles per second, the same frequency as an idling diesel engine.
Sharks are immune to all known diseases.
Sharks and rays also share the same kind of skin: instead of scales, they have small tooth-like spikes called denticles. The spikes are so sharp that shark skin has long been used as sandpaper.
Animals also are either right-handed or left-handed. Polar bears are left-handed - and so is Kermit the Frog.
There are 701 types of pure breed dogs.
There are about 54 million dogs in the US, and Paris is said to have more dogs than people.
Some bird species, usually flightless birds, have only a lower eyelid, whereas pigeons use upper and lower lids to blink.
Fish and insects do not have eyelids - their eyes are protected by a hardened lens.
Flatfish (halibut, flounder, turbot, and sole) hatch like any other "normal" fish. As they grow, they turn sideways and one eye moves around so they have two eyes on the side that faces up.
Measured in straight flight, the spine-tailed swift is the fastest bird. It flies 170 km/h (106 mph). Second fastest is the Frigate, which reaches 150 km/h (94 mph).
