This is a complete, class-tested overview of the biological processes underlying aging at the molecular, cellular, organismal and population levels. Although intended as a textbook of gerontology for advanced undergraduates and beginning graduate students in biological or biomedical fields, Biology of Aging will also be of interest to professionals and general readers with a background in general biology.
