Abstract
Instead of considering aging in terms of discrete hallmarks, we suggest that it operates in four layers, each at a different biological scale. Malfunctions within each layer-and connections between them-produce the aged phenotype and its associated susceptibility to disease.Keywords: Aging; adaptive response; age-related diseases; dietary/caloric restriction; evolutionary fitness
