First, aging increases the probability with time that the individual will die. Second, aging decreases the ability of an individual to withstand extrinsic stresses. It follows, then, that either the timing of death or the age-related decrease in functional properties may be used to measure the occurrence of age-related changes. Death is a singular and acute event in an individual’s life span. Simply knowing its chronological time for one individual gives us no useful information with which to determine the rate of aging of that individual.

The values of Lx and of Tx do not give rise to graphical plots; rather, they are used to calculate the value of ex, the further expectation of life at the beginning of age interval x. Since qx has been defined as a constant in this population, it follows that the average expectation of further life at any age for our hypothetical organism is 5 years. Therefore, a population that dies as result of random predation rather than of senescence generally displays the following characteristics: (1) The number surviving is a decreasing exponential function of time; (2)the age-specific death rate is constant at all ages; and (3) the further expectation of life is constant at all ages, assuming a large enough population size.
