Theories of Aging

  • Marie-Françoise Schulz-Aellen


The descriptions provided so far have given a flavor of the complexity of the process of senescence. In an attempt to understand the various components of aging, and to analyze them critically, scientists have proposed testable hypotheses and constructed theories about the possible mechanisms of aging. These theories can serve as the basis for experimental testing. As Einstein stated: “It is the theory that decides what we can recognize.” The term theory comprises an organized set of observations and concepts that might account for a given process. This is the case for some theories of aging. Other so-called theories of aging could rather be described as detailed observations of the consequences of biological and biochemical processes.
