We either see the parts of our bodies as ordinary, or take them for granted. But we aren’t aware of the amazing things the parts of our body can do — they are more complex and complicated than we realize!
The average life of every blood cell lives up to 120 days. And they move around inside your body pretty fast, as they circumnavigate there in about 20 seconds.
You would not believe it, but a few number of people have eyes whose color is different from one another. This condition is called heterochromia, which is mostly caused by excess or lack of melanin.
Your hair and nails are both made of keratin, a protein consisted of dead cells. Now you know why cutting your hair and clipping your nails never hurt at all — because they’re dead.
Our salivary glands can produce around 1 to 1.6 liters of saliva each day!
Our nose can do amazing things we could never imagine. It can actually distinguish over one trillion different smells and odors! And do you know that the nose is our built-in air-conditioner? It regulates temperature by cooling hot air and by warming cold air. It also filters impurities from the air we breathe — and the dirt inside your nose is the reason picking it!
Our eyebrows and eyelids are thought to protect the eyes from sweat.
Supposedly, it is possible to sneeze with your eyes open — and it is not entirely true that if you sneeze with your eyes open, your eyeballs will pop out of its skull.
But sneezing, as an involuntary act, will just force your eyes to shut. It’s probably because of a reflex. The nose and the eyelids are connected by the cranial nerves. So when you sneeze, the stimulus travels the nerve towards the eyelids and another one down to the nose, triggering your eyelids to automatically shut while you sneeze.
Babies have a combination of 300 bones as well as cartilages. Many of the bones are separate, but will gradually fuse as they grow older.
We may never be aware of them or feel them crawling, but there are actually mites in our eyelashes. They are called “demodex,” microscopic parasitic mites also called simply as eyelash mites. A full-grown adult Demodex folliculorum measures only 0.3–0.4 millimeters (0.012–0.016 inches) long and has eight segmented legs. Their infestation doesn’t cause so much trouble except perhaps for minor skin irritations.
It’s the bacteria that mixes with the sweat and therefore makes it odorous.
A recent study conducted on men found a connection between hirsuteness and intelligence as well as educational attainment. The study concluded that guys who were students or graduates were a lot hairier than men who were not degree holders or men who worked in menial jobs. It also revealed that male students who excelled in their college courses had more hair than those who lag behind in their studies.
