The cycle ends
Other things equal, the death of an old person disturbs us less than the death of a young person, apparently because early death is considered somehow unfair (Kastenbaum, 1975; Roth, 1977). The word death refers to both an event-dying-and the result of this event. It is difficult to distinguish between clinical death and biological death. Clinical death is defined by the absence of vital sings, but after the disappearance of vital sings some biological structures continue to function for an appreciable length of time, and different structures continue to “live” for different lengths of time. Biological death varies, in other words, for different structures in the body. Brain cells are among the first to die when oxygen in the blood is depleted, either because the blood is not oxygenated (as in drowning) or because the blood is not circulated (as in heart failure). Presumably, the mind ceases to function when the brain cells die, although this presumption is challenged in some religions.
