Interesting science trivia about life

Anqi Li

There are many interesting scientific events about life around us in the world.

For example, why is it impossible for a person to sneeze with their eyes open or the strongest and most powerful muscle in the human body is the tongue. Today, we are going to explore these amazing scientific events.

Do you know that the eye muscles of a normal person move an average of 10,000 to 15,000 times a day? We all blink, some more, some less. In general, adults blink 12 to 15 times per minute, and children may have more. In this way, a person blinks more than 10,000 times a day.

Why do people blink? This is actually a physiological need. When you blink, the tears can be evenly distributed on the cornea and conjunctiva, so that the eyeballs will not be dry and can also remove the dust and bacteria in the eyes. If you don't blink, the tear film on the eyeballs will evaporate quickly, and we will feel dry eyes uncomfortable and even stinging and tearing.

The number of blinks is also closely related to people's psychological state. When we are nervous, we blink more, and when we concentrate, we blink less. When people use computers, the blink frequency can be as low as three times a minute.

Water, which is one of the most common substances on earth, an important resource for the survival of all life including humans, and the most important component of living organisms. Do you believe that theage of water has been 300 million years since ancient times? When the water on the earth was first formed, no matter whether it was a lake or an ocean, the amount of water was not very large.

As the water vapor generated inside the earth was continuously sent into the atmosphere, the amount of water on the ground continued to increase. After billions of years of evolution of the earth, finally, the rivers, lakes and seas we see now are formed. The earth is 4.6 billion years old, of course water is 300 million years old.

A left-hander is a person whose dominant hand for writing or using chopsticksis the left hand. Studies show that left-handers make up about one-tenth of thepopulation. Left-handedness is a peculiar physiological phenomenon. According tostatistics, 15 out of every 100 people in the world eat with their left hand, and menaccount for 70% of them.

Diana Halpens, a psychology professor at the University ofCalifornia, San Bernardino, and Stanley Colin, a researcher at the University ofBritish Columbia, reviewed the death certificates of 987 people in two SouthernCalifornia counties and emailed them After asking the relatives of the respondentswhether they are mainly left-handed or right-handed, they found that the averageage of death for right-handed people is 75 years old, while the average age forleft-handed people is 66 years old. Right-handed people live an average of nine years longer.

There are many interesting scientific trivia about life happening around us,and life is not static. We need to learn to observe the interesting things around us.Tolearn or learn more about interesting discoveries about science.
