What is the definition of aging?
Aging is a syndrome of changes that are deleterious, progressive and universal. Aging damage occurs to molecules (DNA, proteins and lipids), to cells, and to organs. Diseases that increase in frequency as we age include arthritis, osteoporosis, heart disease, cancer, and Alzheimer’s disease. The traditional definition of aging is that it is an inevitable process of becoming increasingly disabled that is evidenced by certain symptoms, such as failing memory and less energy. A more modern approach looks at the biological processes of the disabilities associated with aging and the degree to which the physiological deterioration can be prevented or altered.
