In the 20th century, life expectancy did rise radically amongst the wealthiest populations of the world from about 50 years to above 75 years (RGS organization, 2014). In accordance with the National Centre of Health Statistics, men’s’ life expectancy back in the year 1907 was forty-five years. by 1957 the life expectancy rose to sixty-six point four. it reached seventy-five point five in the year 2007 (weblog, 2007). In accordance with researchers at Harvard University, researchers from the World Health Organization in the previous did claim that individuals live longer and healthier lives this day compared to the past. Life expectancy globally did increase from about sixty-four years in the year 1990 to around seventy years in the year 2011 (Fightaging Orgnization, 2013). This study’s data did come from the Medicare Current Beneficiary Survey, which included around ninety thousand men as well as women between the years 1991 and 2009. This data did help researchers to assess people’s health as they aged (Fightaging Orgnization, 2013). According to the U.S Social Security Administration, the population of the United States happens to be graying the same as in most countries. In the year 1950, eight percent of the whole population did have an age of 65 years or even older. That share hit twelve percent in the year 2005 and it is predictable that it will grow to hit 23 percent by the year 2080. The population of the elderly will have more twice the percentage of the whole totality in just above population of the working-age will have shrunk, right from sixty percent in the year 2080 (Reznik, Shoffner, amp. Weaver, 2006). According to Laura Carstensen who is a well-known researcher, most individuals lived in their mid-thirties back in the 1800s. That jumped up to 77 years in the 20th century and this day it is 78 years of age. She added that between four to six generations of a single-family could live at the same time today (Sagon, 2014).
