This term, sometimes known as the longevity factor, is the product of the probability a mosquito survives through the EIP, pn, and its expected life expectancy after the EIP, -ln(p)−1 [8], [8].
The remarkable consistency of these results may stem from a single property: with increasing longevity, certain increase in the retirement age could be seen as a way to accommodate for longer expected life duration, thus keeping the relative proportion of the split between working periods and leisure periods unaffected.
Determine the expected life of the asset.
Appropriate – where a procedure is worth doing if the expected medical benefit to the patient (health status, quality of life, longevity) exceeds the expected negative consequences to the patient (pain, disability, risk of death).
Responses will vary but may include: income, clothes, housing, nutrition, health, life longevity, and education.
"Like anybody, I would like to live a long life — longevity has its place.
These characteristics can be measured by real life longevity tests.
In fact, the average of life longevity [Spelling] in Japan is very high.
However, as sporozoites remain in the salivary glands (Shute 1945; Dawes et al. 2009b) the longer a mosquito survives, the more infectious bites it can make (termed the longevity factor or expected infective life (Garret-Jones 1964)).
They suggested that this increased fecundity arose to compensate for expected decreased longevity in stressing environments.
