People who fall from a building usually hit the ground headfirst?

People who fall from a building usually hit the ground headfirst.

The landing time of a person is relatively short, 3 seconds. During the falling process, it is difficult to adjust the movement to let which part hit the ground first. Generally speaking, the center of gravity of the human body is tilted toward the head. If the height reaches a certain height, There is sufficient time to adjust. It should be said that the probability of landing head first is relatively high, so there is almost no chance of survival for the suicidal person. This is like a hammer with a wooden handle falling from a high altitude, and the hammer hits the ground first.

For a person who commits suicide by jumping from a high-altitude building, if the building is 15 stories high and 45 meters high, the landing time is h=1/2gt?, ignoring air resistance, the landing time is 3 seconds. The high platform diving mentioned above are all well-trained athletes. Before entering the water, their bodies hit the water on the side and their back hit the water, causing damage to their body tissues.

Those who commit suicide by jumping from a high-altitude building may face an innate instinctive reaction. During the fall, they will hold their heads, bend their bodies, and hold their chests. When they land, will their heads or buttocks hit the ground first? It’s very complicated here. Through some case analysis, after someone jumped from the building, there was almost no chance of survival, but there were also people who survived for a few days in the hospital and died.

Extended information:

The vast majority of people who fell from a building and did not die mainly fell from the building in an unconscious state, such as falling while drunk. Their falling floors sometimes reach the 4th to 6th floors. The mortality rate for jumping from a building at this height is as high as over 80%.

However, they fell unconscious and no deaths occurred, and some even suffered only minor injuries. This is mainly because when a person jumps from a building, he is actually very afraid of pain and death. The moment he jumps from the building, his body becomes stiff, and his hands and feet subconsciously move to support the ground. This is a conditioned reflex caused by human fear, and there is no way to avoid it.

So once his stiff body touches the ground at this time, the bones will pierce the human body's arteries, causing massive blood loss and death. Due to the stiffness of the body, the legs made a supporting movement. Under the strong inertia, the leg bones would even pierce the internal organs in the abdomen, causing massive internal bleeding.

The body was stiff and he fell to death, which is enough to show that the person who jumped from the building was still conscious before touching the ground, and the process of death was very painful.
