Facts about the human body.

1. Guess your real age
Human life stared with the production of the egg
that is 0.2mm in diameter, which is equal to a
size of a full stop. The most surprising thing is
that the egg from which you developed was
produced inside your mother when she was
herself an embryo. So consider your existence
even before your mother’s birth. For example, if
your mother conceived you at the age of 25 and
your current age is 20 years than you are
existing since 45 years.
2. Tongue Prints
It’s not just your finger prints that make you
unique from other human but your tongue has
prints too and every individual has a different
tongue print.
3. Skin Shedding
The skin is the largest organ of our body, an
adult man has skin stretched up to 20sq ft.
Humans shed about 1.5 pounds of skin particles
every year that makes 600,000 skin particles
every hour. So by the age of 70 years an average
person will shed up to 105 lb of skin.
4. Babies have more bones than an Adult
It is astonishing but true that a small baby has
more bones than an adult. When we start our
lives as a baby we have 350 bones, these bones
then fuse together when we grow up and in the
end we are left with 206 bones.
Human bones are very strong. A solid piece of
bone relative to a size of a matchbox can support
weight up to 9 tons, that’s 4 times more weight a
block of concrete with the similar size can
support.
5. Renewed Stomach Lining
An interesting fact is that your stomach’s
digestive juices are so strong that it can even
dissolve zinc. Fortunate for us, the stomach
lining is renewed after every 3 to 4 days because
if it wouldn’t the strong acids can digest our
stomach as well. When you blush the stomach
lining also reddens.
6. 25000 quarts of Saliva Production
On average a person produces 25,000 quarts of
saliva in a lifetime. That’s enough to fill 2
swimming pools.
7. Human and chimpanzee has same number of
hair
It would be hard to believe that humans and
chimpanzees have equal number of hair on their
bodies the only difference is that human hair is
so thin and fine that it makes them almost
invisible.
8. Number of Sex cells produced in humans
In females, about ½ a million eggs are produced
on average out of which only 400 would have the
potential to develop into a baby. Men produce
10 million sperms approximately, every day.
They are enough to repopulate the earth in 6
months time.
9. 11 days of sleeplessness can kill you
We all know that we can’t survive without food
and water, but have you ever wondered for how
many days you can live without sleep? You can
survive without sleep for eleven days only, after
that you will fall asleep forever!
Also our height increases up to 8mm while
sleeping. It is assumed that nerds are dreamiest
because people with the higher IQ have a higher
frequency of dreams.
10. Lungs have 300,000,000 million capillaries
There are over 300, 000 million capillaries inside
the lungs, and if you stretch them out end to end
they would cover a distance of 1500 miles that is
equal to the distance from Seattle to San Diego.
11. Blood travels 60,000 miles
Our blood travels a long road. It is said that take
60 seconds for the blood cells to complete their
path. 2,000 gallons of bloods travels a distance of
60,000 miles in the blood vessels. Also with the
gain of every single pound of fat, the traveling
distance increases up to 7 miles.
12. Our nose can identify 50,000 scents
We might not have as sharp sense of smell as a
dog but still our nose can remember 50,000
different scents.
13. Feet can produce a pint of sweat
Did you know that we have 500,000 sweat glands
in our feet which can produce sweat equal to a
pint, every day? That’s enough to fill two glasses.
14. Eyelash mites
At a later age humans can have eyelash invaders
called eyelash mites. These near to transparent
mites can grow up to a size of 1/3rd of a
millimeter. They are usually present at the base
of the eyelash or eyebrow hair and are only
visible under a microscope. Why are they found
inside human eye? These creatures tend to grow
on old skin cells and sebum produced by follicles
of human hair.
15. Blondes have the thickest hair
Blondes have the highest volume of hair out of
all hair colors. The hair color also helps to
determine the thickness of your hair. An average
human has 100,000 hair follicles, where blondes
have 146,000, black haired people have 110,000
and brown haired have 100,000 follicles.
Redheads have the least volume of hair i.e. only
86,000 follicles.
16. Eye movements
The focus muscles of our eyes move 100,000
times in a day, if you compare it to walking it will
make 50 miles. We blink 10,000,000 times in a
year.
