What is the difference between aging and longevity? Distinguishing these concepts helps guide how to live a long and healthy life. To live longer, to live longer, to look and feel young and disease-free is not the same thing. Although our life expectancy is getting longer, people are suffering from age-related chronic diseases for longer and longer. In other words, we will not necessarily gain more years of vitality and health, but will experience more years of disease. With major advances in sequencing technology and analysis algorithms, it has only been possible to define aging and lifetime separately in the last few years. These definitions are essential for improving aging and longevity, and living a long life full of energy and good health. One way to consider aging and longevity is healthy longevity and Health span.
Health span: The part of a person’s overall health in good health.
Lifespan: The life time of a person or animal.
Considering these concepts, the scientific community has proposed some general definitions of aging and longevity, which can be roughly expressed as follows: Aging: The gradual and event-dependent decline in the ability to maintain biochemical and physiological functions. Longevity: the length of life. Now, just because these two concepts are different does not mean that they are not intertwined. It may be difficult to distinguish human biological aging from longevity, because the rate of aging may affect the length of life. Having said that, some researchers believe that longevity and lifespan have nothing to do with health and aging. In other words, there are different forces at work.
