17 Quick Body
Facts That Will Make Your Jaw Drop
Our body is
fantastic. It performs thousands of operations every day which, however
insignificant they may seem, are essential to keep us healthy and to feel good.
In most
cases, we know the functions of our body. However, we ignore many other things
that are of paramount importance and even seem incredible at times.
In this
article, we are going to show you 17 things about the human body that you
probably didn't know about and will make your jaw drop.
1. We have the same amount of hair as chimpanzees
The average
body of an adult man contains the same amount of hair as a chimpanzee. The
difference is in the thickness of the hair, which is much thinner in humans.
Thus, in our case, the hairs have lost their original protective function. The
current condition of body fluff is probably due to the development and use of
clothing that protects us from the cold.
2. Goosebumps
Everyone has
experienced goosebumps many times in their life. It is a pilomotor reflex, a
response that humans had in ancient times to bristle body hair and protect
themselves from the cold or other dangers like animals. It was actually a
magnification of the waist. Of course, this function is now obsolete. Although
we don't have as much body hair, our skin still has the same response.
3. Years of blinking
Humans spend
the equivalent of 5 years blinking. As we know, this action is very important
to our eyes: it is a protection and prevention mechanism. Thanks to this, we
lubricate and rest our eyes, which cannot remain open all the time. Blinking is
also a protective reflex since we usually do it when something is directed at
our faces.
4. Lefties are stronger
Maybe it
comes from physics, left-handed people have more strength when they apply it counterclockwise.
This means that for a left-handed person it will be easier to open a jar than
for a right-handed person. However, to close the same jar, where the force will
have to be applied in the opposite direction, it will be easier for the
right-hander to do so.
5. The stomach stores acid
Our stomach
stores hydrochloric acid, produced by the cells in this area. In industry, this
type of acid is highly corrosive and is used in metallurgy. However, the lining
of the stomach protects us from the harmful effect of the acid, and we
absolutely do not suffer from it.
6. We are a deposit of bacteria
The human
body is a huge deposit of bacteria. In fact, the calculations say that they are
much more numerous - about 10 times more - than the cells. Of course, this does
not mean that all the bacteria in our body are harmful to health. There are
different, some are beneficial and help our body to maintain good health.
7. Naps are good
Who said naps
were bad for your health? This helps us to improve our concentration, our mood,
and our productivity. However, sleeping too long during the day can have
negative consequences. For example, we may feel more tired and irritable.
8. Lots of dead cells
Every day,
our bodies reject a large number of dead cells, mainly from our skin. It hurts
so much that if we collect them for a year, we would get about 2 pounds of dead
skin cells.
9. Sensitivity
As we know,
the human body has a large number of nerve endings that allow us to feel
things. Among these, the most sensitive is found on the lips and fingers, while
the least sensitive is found in the area of the middle of the back.
10. Our hair weighs the weight of an apple
Depending on
its length, our entire hair would weigh between 5 and 200 grams, the equivalent
of a medium-sized apple (about 150 grams).
11. We would survive better without eating than without sleeping
Subject to
having water, you could survive one to two months without eating, depending on
your body fat and other factors. Deprived of sleep, we would radically change
our personality and see our mind-altered after only a few days. The record
observed would be 11 days.
12. We are taller in the morning than in the evening
We would gain
up to 2 cm per day upon waking, or rather, we would lose 2 in the evening ...
Indeed, we would seem to settle down less when lying down than in a vertical
position. Why? Because of gravity.
13. There are not 4 different types of blood groups
We would be
led to believe (wrongly) that our blood groups boil down to O, A, B or AB. In
reality, there are more than 25 groups. The rarest of them comes from a group
of Japanese families.
14. There are more bacteria in our mouths than people on earth
Even with
ultra-rigorous dental hygiene, a single tooth would harbor between 1,000 and
100,000 bacteria. Add to that about 1 billion bacteria in the saliva that we
swallow every day ... Enough to have a furious desire to go and brush your
teeth!
15. The imprint of our language is unique
Like all
other footprints, that of the tongue is unique. The information contained on
this multifunction organ would indeed present identifications of geometric
shapes with a unique physiological texture.
16. Men have fewer taste buds than women
Sorry
gentlemen, who would thought the surface of your tongue is less rich!
17. Soft, brittle nails may indicate an overactive thyroid
If their
white arc (commonly called “moon”) is, in addition to that, almost nonexistent,
your nails can alert you to a potential risk of contracting an overactive
thyroid. Consult to find out.
