This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships between fundamental aging processes and ARDs are still missing. It could also be that the above-mentioned fundamental aging processes themselves are mediated by positive feedback loops. For example, chronic inflammation can amplify itself similarly to autoimmune diseases via cytokines and epitope spreading. Cellular senescence can propagate from cell to cell in a chain-reaction fashion via cytokines and reactive oxygen species. DNA damage may amplify by affecting the genes of more and more DNA repair enzymes. Accumulating intracellular garbage may impair the lysososmal function, leading to ever-accelerating garbage accumulation. However, to test these propositions, longitudinal data on the kinetics of corresponding processes should be obtained.
