Answer 2

Life Expectancy at birth indicates the number of years a new born is expected to live.

Explanation:

Basically,life expectancy at birth implies the expected average number of years any newborn baby will live at the time of the birth,considering the existing mortality trends or patterns would remain the same in the future.However,the life expectancy at birth does not automatically imply that the expected average life span of any individual new born would be the same as the overall average life expectancy at birth of the entire nation.In general,the expected human longevity varies from the overall national life expectancy and is evidently contingent on several factors such as personal lifestyle,nutritional intake,diet patterns,health immunity,weather and climatic patterns and so forth.
