expectancy

 [ek-spek´tan-se]
the expected value or probability of occurrence for a specific event.
life expectancy the number of years, based on statistical averages, that a given person of a specific age, class, or other demographic variable may be expected to continue living.

life expectancy

n.
The number of years that an individual is expected to live as determined by statistics.

life expectancy

the probable number of years a person will live after a given age, as determined by mortality in a specific geographic area. It may be individually qualified by the person's condition or race, sex, age, or other demographic factors. Also called expectation of life.

life expectancy

Longevity, period life expectancy Epidemiology The average length of life of persons in a population; the average number of yrs of life remaining for a population of persons, all of age x, and all subject for the remainder of their lives to the observed age-specific death rates corresponding to a current life table. See Life table.

life expectancy

A statistical estimate of the number of years a person, of any particular age, is likely to live.

life expectancy,

n the probable number of years a person will live after a given age, as determined by the mortality rate in a specific geographic area. This number may be individually qualified by the person's condition, race, sex, age, and other demographic factors.

Patient discussion about life expectancy

Q. what is the life expectancy of a person with chronic bronchioectasis

A. depends on how severe are the infections...how your body reacts to those infections and what is the cause of those infections (cystic fibrosis??). i think only the therapist treating you can estimate. and even so - there are ways to prevent recurring infections. can slow the process of destruction and even stop it completely.

The scientific advances in this area are stunning, and progress in both areas (maximizing physiologic life-span and changing the boundaries of aging) is so spectacular that the possibility for human application of these animal, insect, and test-tube studies in the not-too-distant future by responsible scientists and physicians is very real.
The life-span prolongation will first take place in the developed world (Europe, North America), where the technologies are likely to be available earlier.
Whatever the sequence of adoption of life-extending technologies, whatever calculations and assumptions are used, marked extension of life-span would have a profound effect on world population.
If that notion is accepted, then it follows that the greatest threat to achieving population stability at reasonable levels will not be a failure to control birthrates but rather the extension of adult life-span.
I suggest that we concentrate on conquering diseases and slowing the aging process so people can live out their maximum physiological life-span.
We have no way of knowing what the maximum healthy life-span will become when we reextend human telomeres.
If we doubled the human life-span and other things remained unchanged (however unlikely), we would double population.
But increasing the healthy human life-span will probably increase economic efficiency, lowering economic costs.
In fact, if the average life-span were extended to 82 years, then half of all medical costs would be incurred after age 80.
Currently, medical costs increase along with life-span and threaten to absorb a frightening percentage of the gross national product.
The Life-Span Theory of Control model supports the view that the human tendency is to resist modification to core values and beliefs, hence the use of the primary-secondary distinction within the control model (Heckhausen & Schulz, 1995).
Also, taking different roles through life-span and life-space, as defined by Super (1990), is a learned experience that requires an individual to acquire knowledge and skills during his or her growing process.
