2- The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain.
3- The average human body contains enough:
┗▶ Sulphur to kill all fleas on an average dog,
┗▶ Carbon to make 900 pencils,
┗▶ Potassium to fire a toy cannon,
┗▶ Fat to make 7 bars of soap,
┗▶ Phosphorus to make 2200 match heads, and enough Water to fill a ten gallon tank
3- Your left lung is smaller than your right lung to make room for your heart.
SECRETS OF GENIUS REVEALED !
A team of U.S. scientists discovered what is the key of genius. For several years they have been studying brain structure of people with high intelligence and came to interesting conclusions.
It was discovered that truly ingenious ideas come to those people who think slowly.
At the moment of thinking brain areas, responsible for visual perception and sensory information, are highly concentrated with NAA molecules. These molecules are responsible for originality of thought and creative solutions.
The molecular motion of NAA in people with high IQ is slower than in those with lower intelligence.
Scientists have described the process of generating breakthrough ideas. Due to some structural features of their brain, highly intelligent people think more slowly than others, but almost always find a unique solution to a particular problem.
Incidentally, a scientific genius Albert Einstein was famous for slow thinking. He used to think for hours on any issue, and the results you know…
As well as putting fuel into our bodies, we also need to get rid of stinky waste.
Pee :
★ You pee between 1 and 2 litres of Urine a day.
★ In your life, you pee enough to fill a small swimming pool. That's a bout 45,000 litres.
★ Absolutely fresh pee has no smell. But as soon as it comes out of your body, the urea in it starts to break down and, boy, does it pong !
★ The smell in old pee comes from the gas ammonia. Ammonia is the gas found in smelling salts, fertilizers and explosives !
★ When Full, your bladder swells up like a balloon, and it is just about as thin-skinned.
★ Your pee is mostly water, plus a bit of salt, and the chemical compound Urea.
★ Urea is rich in nitrogen, which crops need to grow. But don't go peeing in fields —farmers have their own supply of urea that they put in sprays.
Toilet Tales :
★ The average human spends between 6 months and a year of their life on the toilet.
★ The average adult goes to the loo about four times a day.
Poo :
★ Of the non-watery bit of a poo, about a third is dead bacteria —the victims of the battle inside to digest your food.
★ Another third is stuff we can't digest, like cellulose (fibre). This helps move turds along, because it gives the gut muscles something to grip on to,
★ The final third is a slurpy mixture of fats, dead cells, salts, mucus and live bacteria. Mmm!
★ Poo is brown because it contains an iron-rich substance called bilirubin, which comes from old red blood cells.
★ Poo with a lot of fats or gas in it floats.
★ Newborn babies' poo is green. That's because they couldn't poo inside the womb, so bile digestive juices have been building up for months with nowhere to go.

| A Human brain |
Number of minutes your brain can survive without oxygen before it starts to die : 4 to 6
Number of seconds you have before losing consciousness due to blood loss : 8 to 10
Number of watts of power your grain generates when you’re awake : 10 to 23
Percentages of oxygen and blood flow going to the brain : 20
The number of miles of blood vessels in your brain : 100,000
The number of synapses for each neuron in your brain : 1,000 to 10,000
Number of neurons in your brain : 100 billion.
★ Brain just looks like a pile of fat spaghetti, but your brain is actually the most amazing things in the Universe.
★ There are more connections in your brain than there are atoms in the Universe.
★ Everyone has their own unique pattern of wrinkles on their cerebral cortex.
★ If you're a woman your brain weighs 2.5 percent of your body weight, on average, while if you're a man it weighs 2 per cent—but men's brains are heavier on average because men are bigger than women.
★ Brain surgeons can operate on a brain while the person is conscious, as the brain does not feel any pain when it is cut.
★ Your brain has about 100,000,000,000 (100 billion) neurons.
★ Each neuron is connected to about 25,000 other neurons.
★ Nerves or neurons carry messages around your body using electricity.
★ If you stung all your nerves end to end, they would measure 75 kilometres.
★ Nerves can carry signals at a speed of 100 metres a second.
★ When you were in the womb, you grew 250,000 nerves every second.
★ After, you're born, very few nerves are made. By the time you're 10, half of them have died off. But don't worry, you've still got plenty left.
★ Your brain knows when you tickle yourself, which is why you don’t bend over laughing.
★ When you sleep, you’re virtually paralyzed because your brain creates a hormone to prevent you from acting out your dreams.
★ It’s not true that humans only use 10% of their brains; each part of the brain has a purpose.

★ The eye of a human can distinguish 500 shades of the gray.
★ The cornea is the only living tissue in the human body that does not contain any blood vessels.
★ Eyes are the most complex organs you possess except for your brain.
★ Eyes are composed of more than two million working parts.
★ Eyes can process 36,000 bits of information every hour.
★ Under the right conditions, can discern the light of a candle at a distance of 14 miles.
★ Eyes contribute towards 85% of your total knowledge.
★ Eyes utilize 65% of all the pathways to the brain.
★ Eyes can instantaneously set in motion hundreds of muscles and organs in your body.
★ In a normal life-span, will bring you almost 24 million images of the world around you.
★ The external muscles that move the eyes are the strongest muscles in the human body for the job that they
have to do. They are 100 times more powerful than they need to be.
★ The adult eyeball measures about 1 inch (2.5 cm) in diameter. Out of its total surface area, only one-sixth is exposed i.e. the front portion.
★ The eye is the only part of the human body that can function at 100% ability at any moment, day or night,
without rest. Your eyelids need rest, the external muscles of your eyes need rest, the lubrication of your eyes
requires replenishment, but your eyes themselves "never" need rest. But please rest them!
★ Eyes are your most precious sense. Care for them properly!

★ It is a very common misconception that "An ostrich egg is the largest living cell" however if you notice, a human being has the largest living cell inside it's own body and that is a "nerve cell".
★ Nerve cells (neurons) are cells that make up our nervous system i.e. brain,spinal cord,nerves etc, they are about 1.5 m, running from the base of the spine to the toes.
★ So, now you can say that a Neuron is the largest biological cell and not the Ostrich egg as "largness" refers to size and not to weight.

Some facts about heart ::
┗▶ Your heart muscles pump so hard that even at rest the muscles of your heart work twice as hard as the leg of a person sprinting.
┗▶ Scientists have discovered that the longer the ring finger is in boys the less chance they have of having a heart attack.
┗▶ The right lung of a human is larger than the left one. This is because of the space and placement of the heart.
┗▶ A shrimp's heart is in its head.
┗▶ Jellyfish, sponges and coral have no heart and no brain.
┗▶ The earthworm (Lumbricus terrestris) has five pairs of hearts. They aren't actually hearts, and biologists don't really call them hearts. They're more like blood vessels that can contract. But books often say that earthworms have 5 pairs of hearts.
★ The DNA of humans is closer to a rat than a cat.
★ Biconcave shape helps active and better absorption of oxygen from alveolus, it also provides more surface area and circulates swiftly through-out the body.
★ Whereas "Sickle-cell disease" of RBCs is named so because of its shape changed from biconcave to sickle-like. This shape not only actively absorbs oxygen but also can get stuck in the blood capillaries due to their pointed edges and a person suffering from sickle-cell disease is always at risk of unpredicted death.
★ Your body is creating and destroying 15 million red blood cells per second!
★ It takes about 20 seconds for a red blood cell to circle the whole body.

★ This is because of the size of right lung being slightly bigger then the left lung as it has to leave some space for your heart also.

A team of researchers compared presereved Einstein's brain to other brains of normal people with an average IQ and found that, Einstein's brain was the same as all the others except in one particular area - the region responsible for mathematical thought and the ability to think in terms of space and movement.
Extensive development of this region meant that Einstein's brain was 15% wider than the other brains studied.
Uniquely, Einstein's brain also lacked a groove that normally runs through part of this area. The researchers suggest that its absence may have allowed the neurons to communicate much more easily.
This unusual brain anatomy may explain why Einstein thought the way he did
Einstein himself claimed that he thought visually rather than verbally and that words did not seem to play a role. Instead he saw more or less clear images of a visual kind.

Brain food ::
★ Your brain only requires 20% of the oxygen and calorie that your body needs even though it makes up only 2% of your body weight.
★ It also requires only 10 watts of power to operate while to light even the most dim bulb you need 90 watts.
★ As brain is 80% water therefore you need to drink a lot of water not for your body but at least for your brain.
Cellular memory is a theory that states the brain is not the only organ that stores memories or personality traits, that memory as a process can form in other systems in the body and can be stored in organs such as the heart. First studied in heart transplant recipients Cellular Memory was noted when upon waking up from surgery, patients would display a strange change in tastes, opinions, cravings, and other mild personality changes. Could it be the organs given to them had some part of the donor's memory left within it !!!!!!
