Exercise 14. Write a summary of the videolecture (about 150 words).

[1] The measure of life expectancy at birth is a statistical measure that represents the expected duration of life for babies born during a given time period, usually one calendar year. Life expectancy is shown separately for males and females, as well as a combined figure. Calculated from death rates observed at every age, it is based on the critical assumption that the age-specific risks of death observed during a given year will prevail for all babies born in that year, for the remainder of their lives. In contrast, life span is the theoretical upper limit to life that would be observed if everyone in the population adopted ideal lifestyles from birth to death and if external threats to life were eliminated. Some researchers believe that there is no biologically determined life span per se, but rather a series of time-dependent physiological declines that may eventually be subject to modification (Encyclopedia of Bioethics, 2004, p.98)
