The Human Body is a treasure trove of mysteries, one that
still confounds doctors and scientists about the details of
its working. It’s not an overstatement to say that every
part of your body is a miracle. Here are fifty facts about
your body, some of which will leave you stunned…or…1. It’s possible for your
body to survive without a surprisingly large fraction of its
internal organs. Even if you lose your stomach, your spleen,
75% of your liver, 80% of your intestines, one kidney, one
lung, and virtually every organ from your pelvic and groin
area, you wouldn’t be very healthy, but you would live.If you were to take all of the blood vessels in your body and lay them end to endYou would probably die before you could finish the project.
2. During your lifetime, you will produce enough saliva to
fill two swimming pools. Actually, Saliva is more important
than you realize. If your saliva cannot dissolve something,
you cannot taste it.
How can you have a taste of success then? To test this, I started filling up the hot tub with spit but I am barely keeping up with evaporation.3. The largest cell in the human body is the female egg and
the smallest is the male sperm.
The egg is actually the only cell
in the body that is visible by the naked eye.That would explain why ovulation is painful.4. The strongest muscle in the human body is the tongue and
the hardest bone is the jawbone.All the time?5. Human feet have 52 bones, accounting for one quarter of
all the human body’s bones.Proves gravity once again, bones go downhill too.6. Feet have 500,000 sweat glands and can produce more than
a pint of sweat a day.How many feet?7. The acid in your stomach is strong enough to dissolve
razor blades. The reason it doesn’t eat away at your
stomach is that the cells of your stomach wall renew
themselves so frequently that you get a new stomach lining
every three to four days.So it would be safe to swallow a razor blade?8. The human lungs contain approximately 2,400 kilometers
(1,500 mi) of airways and 300 to 500 million hollow
cavities, having a total surface area of about 70 square
meters, roughly the same area as one side of a tennis court.
Furthermore, if all of the capillaries that surround the
lung cavities were unwound and laid end to end, they would
extend for about 992 kilometers. Also, your left lung is
smaller than your right lung to make room for your heart.See first answer9. Sneezes regularly exceed 100 mph, while coughs clock in
at about 60 mph.
They would be even faster in an airplane depending on which way you were facing.10. Your body gives off enough heat in 30 minutes to bring
half a gallon of water to a boil.Sounds great! I am trying to cook an egg in my armpit right now.11. Your body has enough iron in it to make a nail 3 inches
long.Which nail is it?12. Earwax production is necessary for good ear health. It
protects the delicate inner ear from bacteria, fungus, dirt
and even insects. It also cleans and lubricates the ear
canal.So your finger won’t get stuck in there.13. Everyone has a unique smell, except for identical twins,
who smell the same.But only to each other.14. Your teeth start growing 6 months before you are born.
This is why one out of every 2,000 newborn infants has a
tooth when they are bornThat is a safety feature for the baby, if they are too late in getting born, they can chew their way out.15. A baby’s head is one-quarter of its total length,
but by the age of 25 will only be one-eighth of its total
length. This is because people’s heads grow at a much
slower rate than the rest of their bodies.Not at first, obviously!16. Babies are born with 300 bones, but by adulthood the
number is reduced to 206. Some of the bones, like skull
bones, get fused into each other, bringing down the total
number.See the answer including gravity.17. It’s not possible to tickle yourself. This is
because when you attempt to tickle yourself you are totally
aware of the exact time and manner in which the tickling
will occur, unlike when someone else tickles you.Koko used to.18. Less than one third of the human race has 20-20 vision.
This means that two out of three people cannot see
perfectly.There are some who cannot see anything.19. Your nose can remember 50,000 different scents. But if
you are a woman, you are a better smeller than men, and will
remain a better smeller throughout your life.I smell, therefore I am20. The human body is estimated to have 60,000 miles of
blood vessels.See first answer again.21. The three things pregnant women dream most of during
their first trimester are frogs, worms and potted plants.
Scientists have no idea why this is so, but attribute it to
the growing imbalance of hormones in the body during
pregnancy.they left out “getting even with their husband for causing the situation”22. The life span of a human hair is 3 to 7 years on
average. Every day the average person loses 60-100 strands
of hair. But don’t worry, you must lose over 50% of your
scalp hairs before it is apparent to anyone.Hair today , gone tomorrow. also see fact number 18).23. The human brain cell can hold 5 times as much
information as an encyclopedia.
Your brain uses 20% of the oxygen that enters your
bloodstream, and is itself made up of 80% water. Though it
interprets pain signals from the rest of the body, the brain
itself cannot feel pain.World book or Britannica ? 20/80 rule. Since the brain is the boss, it makes the rest of the body feel pain. see answer to statement 21.)24. The tooth is the only part of the human body that
can’t repair itself.Teeth are so lazy!25. Your eyes are always the same size from birth but your
nose and ears never stop growing.
So, if you live long enough you would be able to see your ear without using a mirror, but only on the same side as the eye because your nose would be blocking your view of the opposite ear.26. By 60 years of age, 60% of men and 40% of women will
snore.Is it the opposite at 40 years of age?27. We are about 1 cm taller in the morning than in the
evening, because during normal activities during the day,
the cartilage in our knees and other areas slowly compress.Even if we sleep all day?28. The brain operates on the same amount of power as
10-watt light bulb, even while you are sleeping. In fact,
the brain is much more active at night than during the day.Another good reason for earwax, it blocks the brainlight from waking up your spouse as they are snoring.
29. Nerve impulses to and from the brain travel as fast as
170 miles per hour. Neurons continue to grow throughout
human life. Information travels at different speeds within
different types of neurons.Information travels hardly at all in most morons, except false information of course.30. It is a fact that people who dream more often and more
vividly, on an average have a higher Intelligence Quotient.At least in their dreams.31. The fastest growing nail is on the middle finger.That is why it is used to salute fellow travelers in NY, is usually about 3″long and made of iron (see answer number 11).32. Facial hair grows faster than any other hair on the
body. This is true for men as well as women.At last, equality of the sexes.33. There are as many hairs per square inch on your body as
a chimpanzee.So just one per square inch?
34. A human fetus acquires fingerprints at the age of three
months.How do they get them from in there anyway?But good thing that by then NSA knows about it too35. By the age of 60, most people will have lost about half
their taste buds.So be careful where you leave your buds after going out on a tasting.36. About 32 million bacteria call every inch of your skin
home. But don’t worry, a majority of these are harmless
or even helpful bacteria.Thanks to congress and the president there is a pathway for them to become citizens of your body without your approval.37. The colder the room you sleep in, the higher the chances
are that you’ll have a bad dream.See facts 21, 28, 30, 36, 43, 47 and 4938. Human lips have a reddish color because of the great
concentration of tiny capillaries
just below the skin.Good thing they are not outside your skin, that would not be so great.
39. Three hundred million cells die in the human body every
minute.See factoid 36.
40. Like fingerprints, every individual has an unique tongue
print that can be used for identification.See answer 34 and think about when you last heard of a crime being solved by use of a tongue print?41. A human head remains conscious for about 15 to 20
seconds after it has been decapitated.How can you know unless it was your head?42. It takes 17 muscles to smile and 43 to frown.So we are better made for frowning.43. Humans can make do longer without food than sleep.
Provided there is water, the average human could survive a
month to two months without food depending on their body fat
and other factors. Sleep deprived people, however, start
experiencing radical personality and psychological changes
after only a few sleepless days. The longest recorded time
anyone has ever gone without sleep is 11 days, at the end of
which the experimenter was awake, but stumbled over words,
hallucinated and frequently forgot what he was doing.Not true,once I stayed awake for two weeks straight. At least that is how I remember it.
44. The most common blood type in the world is Type O. The
rarest blood type, A-H or Bombay blood, due to the location
of its discovery, has been found in less than hundred people
since it was discoveredI always thought that there were lots of people in Bombay.45. Every human spent about half an hour after being
conceived, as a single cell. Shortly afterward, the cells
begin rapidly dividing and begin forming the components of a
tiny embryo.By then , the NSA would know.46. Right-handed people live, on average, nine years longer
than left-handed people do.Too many wrong L turns47. Your ears secrete more earwax when you are afraid than
when you aren’t.See 1,7,17,21,30,37,41 and 4348. Koalas and primates are the only animals with unique
fingerprints.So what? When did you ever see a koala crime solved by using their fingerprints?49. Humans are the only animals to produce emotional tears.And some can do it at will!50. The human heart creates enough pressure to squirt blood
30 feet in the air.Never try this at home, see first answer.
