INTERESTING FACTS YOU MAY NOT KNOW.
Human Mysteries
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 50
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.
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.
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.
4. The strongest muscle in the human body is the tongue and the hardest
bone is the jawbone.
5. Human feet have 52 bones, accounting for one quarter of all the human
body's bones.
6. Feet have 500,000 sweat glands and can produce more than a pint of
sweat a day.
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.
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.
9. Sneezes regularly exceed 100 mph, while coughs clock in at about 60 mph.
10. Your body gives off enough heat in 30 minutes to bring half a gallon of
water to a boil.
11. Your body has enough iron in it to make a nail 3 inches long.
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.
13. Everyone has a unique smell, except for identical twins, who smell the
same.
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 born
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.
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.
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.
18. Less than one third of the human race has 20-20 vision. This means that
two out of three people cannot see perfectly.
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.
20. The human body is estimated to have 60,000 miles of blood vessels.
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.
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.
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.
24. The tooth is the only part of the human body that can't repair itself.
25. Your eyes are always the same size from birth but your nose and ears
never stop growing.
26. By 60 years of age, 60% of men and 40% of women will snore.
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.
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.
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.
30. It is a fact that people who dream more often and more vividly, on an
average have a higher Intelligence Quotient.
31. The fastest growing nail is on the middle finger.
32. Facial hair grows faster than any other hair on the body. This is true
for men as well as women.
33. There are as many hairs per square inch on your body as a chimpanzee.
34. A human fetus acquires fingerprints at the age of three months.
35. By the age of 60, most people will have lost about half their taste buds.
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.
37. The colder the room you sleep in, the higher the chances are that you'll
have a bad dream.
38. Human lips have a reddish color because of the great concentration of
tiny capillaries just below the skin.
39. Three hundred million cells die in the human body every minute.
40. Like fingerprints, every individual has an unique tongue print that can
be used for identification.
41. A human head remains conscious for about 15 to 20 seconds after it has
been decapitated.
42. It takes 17 muscles to smile and 43 to frown.
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.
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. A-H type has
been found in less than one hundred people since it was discovered.
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.
46. Right-handed people live, on average, nine years longer than left-handed
people do.
47. Your ears secrete more earwax when you are afraid than when you aren't.
48. Koalas and primates are the only animals with unique fingerprints.
49. Humans are the only animals to produce emotional tears.
50. The human heart creates enough pressure to squirt blood 30 feet in the air.

I meant to say my I.Q. is 148 which is supposed to put me in the top 3% of the population, but I still need a reasonable amount of sleep!!
