Life Expectancy is a term that seeks to apply information from the past to predict what might happen in the future. It reflects the health of a country's people and is often used to measure the quality of healthcare they receive. Life expectancy at birth, from a global perspective, is the average number of years a newborn infant would be expected to live if health and living conditions at the time of its birth remained the same throughout its life. One of the best ways to grasp the significance of this important global metric is to understand its History.
