The first reason is that medicine is underdeveloped. At that time, medicine was not developed, so a cold or other minor illness required a person's name. In fact, at that time, not only the emperor's life span was short, but also other ordinary people. Many ordinary people can only live to be thirty or forty years old, which was actually a very common phenomenon at that time, so it was too difficult to live longer as far as the medical situation at that time was concerned. Even if you are the honor of the Ninth Five-Year Plan, even if you have the best medical facilities around you, these medical facilities are nothing now, and it is not easy to live a long life. What's more, there was no vaccine at that time, and bacteria easily entered the human body. Moreover, cleaning supplies were not particularly in place at that time, and things like bowls and chopsticks were easily infected with bacteria, thus breeding diseases.
The second reason is overwork. The ancient emperors were completely different from the current office workers. Now office workers have to go to work every day, but they can rest on weekends, so even if they work hard, everyone will not be overworked. But the ancient emperors were different. Although they eat the best food, they have to worry about national affairs every day. They have no holidays for many years. Even iron men can't stand such fatigue, so some emperors will die too much because of overwork. Even if they are not dead, they will get sick. Mingjun, in particular, has been working hard all his life.
The third reason is too much sex life. In fact, the short life of the emperor has a lot to do with this reason. As we all know, the ancient emperors had three palaces and six courtyards, and there were groups of concubines. The most important thing is that concubines are also the best choice. The emperor is the statue of the Ninth Five-Year Plan, so basically there will be a draft every few years, and these female practitioners are also selected through layers, whether they are beautiful or talented. This is because they didn't control themselves, too much sex, and they died young.
Thus, the emperor is not good. Although they have enjoyed the treatment that others can't, these short decades may not be enough for them to enjoy life. What's more, they have been working hard all these years and have no time to have a good rest. If it is someone else, they can enjoy their old age, and they are basically working hard for political affairs when they are alive. Ancient emperors were difficult to do, and good emperors were naturally more difficult to do.
