The attributes of aging include a variety of interconnected molecular and cellular mechanisms that act jointly to control the aging process. Thus, aging has been characterized as a progressive degenerative status accompanied by processes like stem cell exhaustion, tissue inflammation, extracellular matrix modifications, cellular senescence, and metabolic dysfunction. These cellular and tissue modifications reflect inherent molecular deviations in mitochondria, epigenetics, DNA maintenance, proteostasis, intercellular interactions, and nutrient sensing, which give rise to genomic instability and impairment, including telomere dysfunction. Aging is broadly defined as a gradual functional decline in the living organism's intrinsic ability to defend, maintain and repair itself in order to keep working efficiently, and has attracted attention throughout the history of civilization. The health and survival of an organism presents a dynamic equilibrium between the processes of damage and repair, alteration and maintenance, a conventional concept of which is homeostasis. This concept, recently replaced by homeodynamics, involves the constantly changing interrelations of body constituents while an overall equilibrium is maintained. Thus, aging is characterized as a multidimensional process involving a gradual contraction of the homeodynamic space. It affects many different aspects of life, including physical health, cognitive functioning, emotional well-being, and social relationships. Therefore, it is important to consider the multidimensional nature of aging when designing interventions and policies aimed at promoting healthy aging. Furthermore, aging is influenced by multiple factors, including genetics, lifestyle aspects such as diet, exercise, and stress, environmental factors such as pollution and climate change, and social factors including social support and socioeconomic status. Understanding the complex interactions between these factors is essential for promoting healthy aging. There is a consensus that aging is associated with two key aspects: (i) the progressive decline of numerous physiological processes, such as the body's ability to accurately regulate homeostasis, and (ii) the enhanced risk of developing severe diseases like cancer or cardiovascular disease. However, while aging is a major risk factor for many chronic diseases, it is important to recognize that aging and disease are not synonymous. Many older adults maintain good physical and mental health well into old age, and there is growing interest in promoting "successful aging" by focusing on factors that contribute to overall health and well-being. Researchers have distinguished between two categories of age: the chronological age based on the birthdate, and the biological age, which measures the true age at which the cells, tissues and organs appear to be, based on biochemistry. While it is impossible to alter the chronological age, there are ways to manage the biological age. There is growing evidence that interventions such as lifestyle adjustments, medical treatments, and social programs can help promote healthy aging and extend the lifespan. As our understanding of the aging process continues to advance, it is likely that new interventions will emerge that can further improve health and well-being in later life.
