The human body database never expected that 80% of the brain is water

The saying "water in the head" is not entirely true, because the brain is 80% water. Are you familiar with body indicators such as height and weight? There is more to our bodies than just these numbers, which are not only very interesting to look at, but also can change our lives.

1.4 kg – weight of the head

The head weighs 1.4 kg, which is about the same weight as a laptop. However, we cannot judge a person's thinking ability by the size of his head. For example, Einstein's head weighs only 1.2 kilograms.

The brain is 80% water, 25% of which is used for oxygen and sugar circulation in the body to replenish nutrients. When we reach the age of 18, our brains stop growing, so it is impossible for them to store memory larger than a 4G (4194304 n megabytes) laptop.

1 minute - Number of times eyelashes flicker

28 grams – the weight of the eyeball

The eyeball weighs 28 grams. Reading text on a computer is 25% slower than reading a book or newspaper, and men blink 50% less than women when looking at a computer screen.

If you don’t believe me, try it three times in a row.
