Biology of Aging

Research Approaches

The areas of interest that fall within the purview of the biology of aging mirror the fascinating areas of biology today. Aging as a process, or set of processes, affects virtually all of our bodily organs and systems. At the most basic level, some portions of our aging patterns are set in our genes. The reliable differences in the life spans of various species are clear evidence of genetic "programs" that set the general boundaries of species life span. The environment modifies these boundaries, but guppies do not live eighty years, and humans often do. Genes are important in the differences in longevity between individual members of a single species (e.g., long- and short-lived humans), but environmental factors play a major role in these differences. Living in a toxic environment or making deleterious lifestyle choices can have a significant effect on individual longevity.
