    Disengagement theory was formulated by Cumming and Henry in 1961 in the book Growing Old and was the first theory of aging that social scientists developed. [5] Thus, the theory has historical significance in gerontology. Since then, it has faced strong criticism since the theory was proposed as innate, universal, and unidirectional. [6]

    The bargaining theory of depression is similar to the honest signaling, niche change, and social navigation theories of depression described below. It draws on theories of labor strikes developed by economists to basically add one additional element to honest signaling theory: The fitness of social partners is generally correlated.

    The theory is based on the idea that ageing occurs over time due to the damage of the DNA. As an example, studies of mammalian brain and muscle have shown that DNA repair capability is relatively high during early development when cells are dividing mitotically, but declines substantially as cells enter the post-mitotic state. [28] [29] [30]

    The mutation accumulation theory of aging was first proposed by Peter Medawar in 1952 as an evolutionary explanation for biological aging and the associated decline in fitness that accompanies it. [1] Medawar used the term 'senescence' to refer to this process.
