In the chart we are plotting the cross-sectional relationship for the years 1800, 1950, 1980, and 2012. Beltrn-Sncheza H, Crimmins E, Finch C. Early cohort mortality predicts the rate of aging in the cohort: a historical analysis. The arrows connect these two observations, thereby showing the change over time of both measures for all countries in the world. An alternative approach consists in estimating the average length of life for a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at one particular period commonly a year. Life expectancy estimates that describe the population as a whole also suffer from a lack of reliable evidence gathered from these periods. Study hard just for another 2 years to prepare for IIT, after that life would be heaven.
