Scientists are still baffled today as to why DNA and cells regenerate over years, and then suddenly everything starts to fail.
As they function, organs and cells fascinate them even more.
In order to understand this, as Blic writes, we need to know interesting facts about the human body.
Here's what Discovery Fit&Health reveals:
We remember smells
Dogs and cats have better noses, but ours can also remember 50.000 different smells.
Long intestines
The small intestine is about four times longer than the height of an average person - from 5,5 to 7 meters.
Even longer blood flow
Blood travels far. There are about 96.000 kilometers of blood vessels in the human body. And the heart beats about 100.000 times a day.
Bacteria
Every 2,5 square centimeters of skin is a habitat for about 32 million bacteria. Fortunately, most of them are not only not dangerous, but also help our health.
Sneeze rate
The air we tear up can reach a speed of over 160 kilometers per hour. Another reason not to sneeze without covering your nose and mouth.
We could fill swimming pools with saliva
During an average lifetime, we produce about 23.000 liters of saliva, which is enough for two swimming pools.
Loudness of snoring
By the age of 60, about 60 percent of men and 40 percent of women will snore. The volume of snoring is on average 60 decibels, which is the volume of ordinary speech, but it can also exceed 80 decibels, which is equal to the volume of a pneumatic drill with which we drill concrete. A noise level above 85 decibels is dangerous for the human ear and health in general.
Blondes have the most hair
Hair color affects hair density, and blonde hair (natural) is the densest. There are about 100.000 follicles on the average human head, each of which can produce 20 separate hairs during a person's lifetime. People with black hair have about 110.000 follicles, and those with brown hair have the least - about 86.000 follicles.
Fingernails grow faster than toenails
The more they are exposed and the more often they are used, the faster the nails grow. The nails on the hand you write with grow the fastest, especially those on the longest finger.
