How long does a person live? What factors determine it?

Heredity. Children generally inherit some characteristics of their parents more or less. Life expectancy is also hereditary, and genetic factors can be said to be an important factor in determining whether to live longer. The above ordinary parents or immediate family members live a long life, and the next generation of children may live a long life, but the death caused by external forces is excluded.
