Numerous studies have been conducted on various aspects of the longevity and life expectancy [estimated age of mortality] of humans. These studies include: focusing on the ways in which the lifestyle humans adhere to can alter a person's estimated age of mortality and how said lifestyle can affect the quantity and quality of a person's life , how humans can live longer [i.e. longevity] and predict how long someone who has succumbed to disease is left to live. On the contrary, given the various diseases, viruses and dangers to which we are exposed daily as human beings, it is implausible to determine an irrefutable death day of every individual in the world; until death succumbs. Foster (2010) defined the estimated age of mortality accordingly: the probability of survival for 1 year, plus the probability of survival for 2 years, plus a series of similar terms up to the oldest possible age, plus 0.5 to take into account that the estimated age of death will be halfway between two birthdays. (p. 112) Elaborately, the estimated age of mortality is the length of time a person can expect to be alive at a given age (Arias, 2014). To understand the estimated age of mortality of various [racial] population groups, lifestyle factors should be studied in collaboration with each group. In 2009, Arias (2014) determined that the estimated age of mortality for Caucasian males was 76.4 years. According to Hooyman and Kiyak (2011), the estimated age of mortality of Caucasian males falls into the old-old category. The estimated age of mortality of Caucasian males is apparently higher than the estimated age of mortality of African American males by approximately 5.3 years (Arias, 2014). The difference in mortality by age between Caucasian and African American males par...... half of article ......Geruso, M. (2012).
