still remembers when "Titanic" entered thousands of households in 1998 and made the love myth of every couple, the picture in your mind will become the happiness you can never erase.
What a poignant love story, after enjoying a set of video illustrations, let's get to the point.
Why hasn't the Titanic been salvaged yet?
The Titanic sank at a depth of 3,700 meters in the Atlantic Ocean. The water pressure was so great that it took seventy-three years just to find its traces. It can be seen that it is very difficult to salvage the hull of this cruise ship.
In addition, the ship hit an iceberg again at that time. When the hull sank, the entire hull was broken into two pieces. In addition, after more than 100 years of seawater corrosion and the decomposition of microorganisms in the water, the wreckage of the hull was almost the same as that of . The seabed is integrated and has no salvage value anymore. Therefore, the exploration of the Titanic will stop there, let the sleeping continue to sleep, and the good and sadness will continue to sleep.
Why are humans born only crying but not laughing?
all say that a smile is the most beautiful language of human beings, and they also say that "a smile is the most beautiful language", "a smile is ten years old" and so on. Why do you suffer when you are a relative?
If we start laughing at birth, we must have forgotten to drink " Meng Po soup "! It turns out that when the baby is in the mother's womb, there is no air in the lungs. The oxygen needed by the body is obtained from the umbilical cord. After birth, the chest cavity will slowly expand, and then the lobes of the lungs will slowly open.
When a baby takes its first breath of air on its own, the air in the lungs hits the vocal cords, and the vocal cords vibrate to make a cry. On the contrary, if the baby is born without crying, it is dangerous, so the cry also means that the baby is safe and healthy. So was your first cry when you were a child spontaneous or was it beaten?
