- Biological Theories of Aging
Modern biological theories of aging in humans fall into two main categories: programmed and damage or error theories. The programmed theories imply that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development.

22 Αυγ 2020 · Many theories currently trying to explain aging processes and many biomarkers are identified to measure aging and its evolutionary stages. Theories and biomarkers are not studied to extend life span but to guide therapeutic choices and optimize patient management and personalization of care.
Here, we discuss the evolutionary aspects of aging and a selection of theories founded on a variety of biological functions that have been shown to be involved in aging in multiple model organisms, ranging from the simple yeast, worms, flies, killifish, and rodents, to non-human primates and humans.
on nutritionally balanced but sparse diets, containing 30 to 40 percent fewer calories than a normal diet, has been shown to reliably increase the average and maximum lifespans of a range of organisms, including worms, insects, and rodents. It is currently under investigation in primates.
Aging can be seen as an irreversible, time-dependent, functional decline that converts healthy adults into frail ones, with reduced capacity to adjust to everyday stresses, and increasing vulnerability to most diseases, and to death (1). As far as anyone knows, the longest anyone has ever lived is 121 yr.
