HARD-WORKING HEART
The
heart is the hardest working muscle in the body. Every day, it creates enough
energy to drive a semi-truck over 18 miles (30 kilometers). Over a lifetime,
that’s equivalent to driving to the moon and back.
AMAZING BRAIN
The
brain is 60 percent fat, but it still works hard. At any given time, your brain
can generate up to 25 watts of power – that’s enough to power a light bulb.
GROWING SKIN
Skin
is the human body’s largest organ and is constantly renewing itself. Your skin
sheds 50,000 cells every minute. Over a lifetime, that piles up to 40 pounds
(18.1 kilograms) of skin.
THOUGHT POWER
Your
brain is always working, and it is actually more active while you’re sleeping.
Scientists say the average person has roughly 70,000 thoughts each day.
SHRINKING BONES
You’re
born with more than 300 bones, but by the time you’re an adult, you have just
206. This is because some of the bones fuse together.
WOMB WITH A VIEW
Babies
in the womb grow 8,000 new brain cells every second. Newborn babies can
recognize their mother’s face after just a few hours.
INCREDIBLE SENSE
Scientists
have discovered that the visual cortex of blind people can rewire itself to
respond to stimuli received through touch and hearing, helping them to
"see" by touch and sound.
UNFEELING BRAIN
The
brain itself doesn’t have any pain receptors, so it doesn't feel anything. That
is why surgeons can perform open brain procedures on patients while they are
awake.
PUMP POWER
During
an average lifetime, the heart will pump nearly 1.5 million barrels of blood. A
pumping human heart can squirt blood 10 yards (9.1 meters).
FAST SNEEZE
The typical human sneeze travels at just under 40 mph (64
kph). That’s the same speed as a running tiger!
LONG ARTERIES
If
your arteries, veins and capillaries were laid out end to end, they would
measure 62,137 miles (100,000 kilometers). That’s nearly enough to stretch two
and a half times around the planet!
GROWING HAIR
Your
hair grows nearly one-quarter of an inch (6 millimeters) every four weeks and
keeps on growing for up to six years. The hair then falls out, and another
grows in its place.
AMAZING MEMORY
Smell
is the oldest of all the senses - before sight, hearing or touch, creatures
evolved to respond to chemicals around them. Your brain can remember over
50,000 different scents.
AGING BRAIN
The
human brain is the most sophisticated thing in the known universe. Humans have
more brain cells at the age of two than at any other point in their lives, but
it takes nearly 20 years for the brain to mature.
IRON MAN
There is enough iron in a body to make a metal nail
measuring up to three inches (7.6 centimeters) long.
EYE FOR DETAIL
If the human eye were a digital camera, it would have 576
megapixels. An eye can distinguish about 10 million different
colors.
WATER
In a lifetime, a person drinks 20,000 (75,000 liters)
gallons of water.
POOL OF DROOL
An average person produces about 1.8 pints (one
liter) of saliva a day or 25,000 quarts (23,658 liters) of saliva in a
lifetime. This is enough to fill two swimming pools.
EARS AND NOSE
ALWAYS GROW
Did you know that one’s ears and nose never stop
growing?
MILES TO GO
If uncoiled, the DNA in all the cells from the human body
would stretch up to 10 billion miles. That’s the distance
from Earth to Pluto and back or 6,000 trips from Earth to the moon.
LONG-TERM STORAGE
SPACE
Your brain’s long-term memory, which develops until the
age of 40, can hold as many as 1 quadrillion (1 million billion) separate bits
of information in a lifetime.
BEAT-BOPPING HEART
The pulse of your heartbeat changes according to the
music you listen to.
TONGUE PRINT
Just like fingerprints, every person has a unique tongue
print.
TASTY TREATS
Your mouth contains around 10,000 taste buds, most of
which are located on and around the tiny bumps on your tongue. However, the
sense of smell is necessary for taste, too
COLOR OF BONES
Did you know the color of the human bones are actually
range from beige to light brown? The bones you see in museums are white in
color because they have been boiled and cleaned.
A CHARGED HEART
Since a human heart has its own electrical impulse, it
can continue beating for a period of time even if it is separated from the
body.
