The phrase "normal age at death" refers to the age range at which individuals typically pass away. However, there are several alternative terms that can be used to describe this concept. "Life expectancy" is a common term used to indicate the average age at which individuals in a specific population are expected to die. "Mortality rate" refers to the percentage of individuals in a given population who have died within a specific time frame, and "life span" is the maximum potential length of an individual's life. Other synonyms include "usual lifespan," "average mortality age," and "typical death age." The use of these alternative terms can provide a clearer understanding of the statistical patterns of human life expectancy.
