Why do people die, what causes them

All living things in the world are made up of cells, and cells are very important because they store a lot of information about their operations. Some cells recover if they are damaged, but others do not, such as brain cells; When cells are no longer able to reorganize, the organs to which they belong will gradually lose their function. In this case, the body will not function properly and its functions will slowly decline and die.

There are two main causes of human death: disease and degeneration. External factors such as bacteria can damage the cells in the human body, and if the cells do not recover, that part of the organ begins to lose its function (each organ in the body has its own unique function), which will affect the normal functioning of the whole body.

If the body doesn't function properly, we die. Another factor is cell degeneration, each cell knows their lifespan, a phenomenon called program death, when cells have been working for a period of time, cells begin to fatigue, decline and even die. At this time, the organs slowly lose their function, so that we degenerate and die.

In fact, any living thing in the world will die, but there are different lifespans, some are as short as a day or two, some can be as long as hundreds of years, but eventually they all die. It should be so, hopefully been.

What is life? I believe that many philosophers still can't be accurate, and most normal people will always sigh that time flies, and time flies, and since ancient times, many people have been extremely poor all their lives.

Because the various organs of the human body will slowly age due to the problem of age, and finally the various organs will fail and cannot be operated, and the blood will not circulate, and the person will die!

Human death is a natural law, and after a certain period of time, various organs of human beings will stop working, and human beings will lose their lives and die.

The reason why people die is that people are the same as everything in the world, there is a cycle of life and death, how can they live forever.

As a result, the human body will gradually renew its own tissues at a slower rate than aging, so people will die. According to some data, the lungs begin to age at the age of 30, and other organs are later. Death is inevitable when the main organs of the human body lose their function.

In addition, the accumulation of metabolites in the body is also a cause of aging and death.

Finally, human cells are subject to apoptosis, which is an active death controlled by genes. The death of an individual human being leaves more room for victory for his offspring, which is beneficial to the continuation of the race from an evolutionary point of view.

1.Natural angles. This is a law of nature that cannot be violated.

2.Medical perspective. At present, it is more popular to say that human cells will inevitably make mistakes in the process of self-replication, and when these errors accumulate to the point of no return, the person dies (this statement seems to be flawed, because according to research).

After the age of 90, people will not continue to age).

3.Environmental perspective. If people don't die, how can resources be enough?

4.Theological perspective. A person who lives his life on earth will be judged after death.
