Is Death Natural? :: essays research papers

Is Death congenital?Many of the most beautiful and meaningful facets of life are the bearing they are because they are ephemeral.I know that death is natural life-time runs its course before coming around again. Something present in or produced by nature is natural, much(prenominal) as an earthquake or typhoon, or a poisonous mushroom. Death is natural in the sense that to conk is to conform to the ordinary course of h of age(predicate) things in nature.Death has been sculptured as an exponential increase in the rate of illnesses with age.Even with no micro-organisms attacking, the body is not well enough designed to function indefinitely. Something always breaks down eventually. What breakdowns, how many, and when they happen, is randomly distributed among individuals, except for conformance to average delays which may defy been sculpted by evolution.Some of those functions our medicine roll in the hayt re-establish or substitute for and some(a) of those are necessary fo r life.In general, death is an unremarkable event in nature. To break up of "natural causes" is not to expire in old age, as is the case in modern human societies, but to typically die young.Average human life spans between 20 and 30 days for most of our species history. Most people today are thus living highly unnaturally long lives. Because of the high incidence of infectious disease, accidents, starvation, and cutthroat death among our ancestors, very few of them lived much beyond 60 or 70. There was therefore little selection pressure to evolve the cellphoneular repair mechanisms (and pay their metabolic costs). As a result of these lot in the distant past, we now suffer the inevitable decline of old age damage accumulates at a faster pace than it can be repaired tissues and organs begin to malfunction and then we die.It may exhaust out to be impossible to live eer, strictly speaking, even for those who are lucky enough to survive to such a time when technology h as been perfected, and even under ideal conditions. The amount of matter and energy that our finish can lay its hands on before they recede forever beyond our reach is finite in the current most lucky cosmological models.As for age and death, one of the biggest factors actually has to do with cell replication. Most of our cells are not meant to live forever . We are meant to die. Your cells divorce and divide and divide and their daughter cells do the same, so one and such forth.
