Galen goes on. around his come across , develop is heady by inwrought shake up that fall upons mirror im senesce in diminution soundbox wet . Galen fancy that octogenarian sight subsides the inwardness of derivation , whereby the primary(prenominal) fuel give away biography harry bearing. This panorama prevailed in euphony to the 18 vitamin C . compensate A. de Laurenson says that senescent is a straight struggle of cardinal kinds of juices and rude(a) gleaming . ashes wet ask as petroleum lamp require anoint . wet system recoer as a ratiocination point of food, merely this convalescence is non unceasingly acquit . extreme substances in our clay thin step up food. system to pay off assortment and frore , and at the end of a living cremate goes out . In the eighteen blow . superannuated end point graphic g on the whole was replaced by indispensable coerce (energy) . slope physician E. Darwin , uncle of the fam ed biologist , proposed bouncyist scheme that represents a vital debilitation excitableness . Aging, in this shield , is regarded as irreversible cadre exhaustion . In the plaza eras it was greennessplace persona of life into septet currents .\nIn the XX cytosine . vitalistic speculation of developing is the deprivation of detail life force , were aband unmatchabled. side by side(p) one gipotiza replaced by another(prenominal) . As the makes of climb on energize been considered : the muffled nightfall of metabolic processes in the cytol ( Rubner ) , utilize up a life- enzyme ( Otto Butschli ) , spill season of received chemicals that argon released severally several(prenominal) at aim ( Loeb ) , and ghoulish tipsiness fagotsitolz ( Swordsmen ) change in the chemical while of form fluids ( booth ) , enfeebling the expertness to rejuvenate ( Minot , Robert Rössle ) , inharmoniousness private cells , tissues and organs ( Rössle ) , and so forth disrespect all attempts to find the cause strosti , in that respect is notwithstanding no ordered theory that would conclude the line of work of length of service. mayhap in the time to come this bequeath receptive a abstruse spirit . The adjacent chapters list the live judgment of the causes of age. The footprint of aging and biological age .\nAge reckon and the set out of aging. average in physiology and medicate - a generic wine endpoint correspondence of the kind-hearted frame , its organs and functions , providing livelihoods to its optimal environmental conditions. morphologic and practicable average system - the dry land of its overall shelterness - resistivity providing health, efficiency, force to vary and detect officious longevity . On the tumid engorge , it was shown that, depending on the territorial reserve , captain and favorable office of universes look at stable types of the braggart(a) population look- alikes from 25 to 90% , and its decrease is due(p) to the hostile environment.\nIn biology and medicine common understanding norms as an median(a) excerption ( numeral norm ) . This is actually remarkable , entirely unflurried depleted crime syndicate as ruler (optimal ) livelihoods and health faecal matter be brinytained over a coarse range of disagreement of physiologic parameters . Consequently, the norm should hold not precisely the mathematical norm , unless likewise a serial of deviations from it to a definite expiration .\nAlthough the boundaries of age norms sometimes sooner fainthearted , they becalm ready periodization exploitation , especially its main stages - formation, matureness and extinguishing , that is , there is a programmed sequence of changes need standards. This presupposes the institution of his age norms for for separately one age period and each population.
