Do astronauts really grow tall in space!

-


When we reach a certain age, we see that the growth in height stops. But it is not like that in space, if you go there, the height increases, which is strange to believe, but this is literally true. An example of this is the astronauts who have travelled to space so far. Originally the same height, NASA astronaut Scott Kelly was two inches taller than his identical twin brother Mark after living for nearly a year aboard the International Space Station.

When on the ground, gravity puts pressure on the discs in our spine. This level of gravity in space makes them stretch. Astronauts will grow a few centimeters taller because of this. If you return to the ground again, you will reach the original height. That is why many astronauts say that they are facing back pain problems after returning to earth. Another interesting thing is that space radiation causes slight changes in the DNA of many astronauts.

Because like water is needed to grow a plant, money is needed to maintain love and relationships. That's why Karls Marx said that "All human being relations are economical". 99 percent bonds that exist now are all financial bonds. every day we see on TV or in the paper that the property is not given to the son, the property is not distributed equally, or the husband kills his wife fo

 A man life is a hectic life, starting from waking up early and going to bed late at night,man will always thinking about work or thoughts about life. Man is a creature of hope, so he always relies on something. First, he hopes to fill his stomach with three pages, then he keeps thinking about good clothes, own house, own car, bank balance and so on. That is why the average life span of man has dropped by 50-60 years. In those days, people usually did not get blood pressure or diabetes, but today's competitive world, if you reach the age of 35 years, you don't know when which kind of disease will occur  All this is a height but the life of middle class is a height, as a middle class family 20-30 thousand rupees will be earned if the man work hard from morning to evening for the whole month.
