Why do people die?

Why do people die?

The human body is made up of many things, including muscles, bones, and internal ovals. They are also made up of very small cells.

Humans live about 70 to 80 years on average, but cells do not live that long. Old cells in the body die and leave the body in urine. Then, new cells are born to replace the dead old cells. In this way, human cells are always being gradually replaced by new cells.
However, if this process is repeated over and over again, the same cell may fail to be created.
When we are young, such failures are rare, but as we get older, they become more frequent. The large number of poorly formed cells that result from these failures impairs the function of various parts of the body, and finally, the cells die. Finally, they die. It is not yet clear why we make more mistakes as we get older.
Basically, all living things die for this reason. No living thing can live forever.

It is said that animals with larger brains in relation to their body size live longer, but there are still many aspects of the lifespan of wild animals that are unknown because they have not been studied in detail.
