Ancient times will always be war, the turn of the era of chaos per capita life expectancy are not high. We all know that China's vast territory, from the primitive society to the slave society to the feudal society, the development of society is always inseparable from the war, once the war will be a lot of young people into the army, some very early sacrifice, in the Three Kingdoms period, the average life expectancy is probably only 36 years old or so, because of the Three Kingdoms is more chaotic, the seven warring states are always thinking about how to fight to seize more fiefdoms, although the When we read the playbook, we found that many characters lived quite a long time, that's because their status was higher, and they didn't need them to go to battle to kill the enemy, while most of them sacrificed their lives on the battlefield, especially the young people. So turning chaos leads to a lot of people sacrificing their lives, and the per capita life expectancy will be very low.
Ancient times advocated early marriage and early pregnancy, which went against the law of nature. We all know that in ancient times women were married at the age of fourteen or fifteen, and then get pregnant and give birth to a child, but this greatly violates the physiological characteristics of human beings, pregnant mothers themselves are not fully developed, and at this time they will give birth to a child will greatly increase the probability of their death. In addition, the birth of the child in the mother's fetus because of the poor development, so they also quickly face the risk of premature death. This is a terrible thing.
Ancient times were characterized by poor resistance to natural disasters and low levels of medical care. The development of technology in ancient times was very slow, many small illnesses and pains are easy to cure in modern times, but in ancient times it is very difficult, and the low level of medical care also led to a lot of people died very early, and in ancient times there are always natural disasters, such as mudslides, earthquakes, typhoons, people don't know how to resist them, so it led to a lot of people died.
We should be glad that we are living in the twenty-first century, and we should also cherish the life we get now and study hard to return to the society.
