Definitions
Aging is a process resulting from the accumulation of multiple changes occurring in cells and tissues leading to a progressive decline of physiological function and responsible for an increased risk of disease and death (see “Aging Mechanisms”). Antiaging strategies are interventions intended to slow the aging process and prolong life span.
Overview
A number of theories have been proposed with the thrusting aim to explain the aging process (see “Aging Theories”). They substantially fall in two main categories based on different concepts of aging (Libertini 2015).
For the first interpretation, aging (i) is the cumulative result of various degenerative processes, (ii) is not adaptive (i.e., it is opposed by natural selection), and (iii) is not a consequence of specific mechanisms genetically determined and regulated.
For the second interpretation, aging (i) is...
