The convenience of modern science and technology makes modern people lazy, physical fitness is not as good as before, science and technology make people progress at the same time make people's bodies become "weak", and people in ancient times compared to us are more fragile, weaker, although there is science and technology can prove the progress, in the support of modern science and technology, our average life expectancy is longer than the people of the feudal dynasty, or even doubled, this is the progress of science and technology, but also the proof of human evolution, but many times we find that we are somewhat weak for ancient people, Especially the embodiment on the physical level.

The excavation of the Terracotta Warriors of Qin Shi Huang allows us to see the appearance of the soldiers of the Qin Dynasty, a large number of excavated terracotta warriors let us find a strange phenomenon, why their average height is so high, almost everyone is a big Han, is it that in the Warring States period, people's average height is so high, and in the history records or excavations of the divine weapons we found that the weapons used by the ancients are long and heavy, and the strength and size of modern people are difficult to match such conventional weapons, is it that our modern people are getting weaker and weaker? From the perspective of historical development, it may be like this, and the decrease in average height is not only in modern times, as early as the Tang and Song Dynasties, there was a significant decline in per capita height, why is this?
Tang and Song dynasties are famous in our history, the Tang Dynasty is a prosperous dynasty, radiating the surrounding small countries is a model for other dynasties to learn, people live and work in peace, life is guaranteed, although the Song Dynasty is weak, but the economic strength is proud of history, people's lives have also risen to a new level, why did people's average height decrease after the Tang and Song Dynasties, is this the physiological embodiment of being born in distress and dying of happiness?
In view of such a situation, we have speculated, is it that the successive years of war and chaos before the Tang and Song Dynasties caused people to have to work harder for life, in such a living environment, people force their genes to become excellent in order to survive, the requirements of the army, the cost of life are the pressure of people's progress, this time genes are more excellent, war is the premise of promoting human progress? There are also many objections to this view, in modern life, people in places where wars and chaos occur are more difficult, food and clothing have become a problem, how to better develop themselves, this is unrealistic conjecture.
There are also people who think that female foot binding in the Tang and Song Dynasties is the culprit of people's average height reduction, the study found that foot binding mainly appeared in the late Northern Song Dynasty, and was respected in the later dynasties, foot binding is a bad habit of feudal society, which is the wear and tear of human nature and the destruction of the body, but such torture will not affect the genes, why the average height of people after the Tang and Song Dynasties decreased, there are many conjectures, what may be the reason for you.
