Maintenance theories of aging refer to the various strategies and mechanisms that organisms use to preserve their cells, tissues, and organs in good condition over time. Some common synonyms for maintenance theories of aging include longevity theories, anti-aging theories, and geroprotective theories. These theories can be broken down into subcategories such as cellular repair and maintenance theories, immunosenescence theories, and mitochondrial theories. By understanding the underlying processes of aging, researchers hope to develop interventions and treatments that can extend healthy lifespan and prevent or delay age-related diseases. Maintenance theories of aging provide a framework for scientific exploration and innovation in the field of aging research.
