  1. Senescence

    Senescence or biological aging is the process of accumulative changes to molecular and cellular structure that disrupts metabolism with the passage of time, resulting in deterioration and death. Senescence occurs both on the level of the whole organism as well as on the level of its individual cells. The science of biological aging is biogerontology. Albeit indirectly, senescence is by far the leading cause of death. Of the roughly 150,000 people who die each day across the globe, about two thirds—100,000 per day—die of age-related causes; in industrialized nations, moreover, the proportion is much higher, reaching 90%. Senescence is not the inevitable fate of all organisms, and animal organisms of some groups even experience chronological decrease in mortality, for all or part of their life cycle. On the other extreme are accelerated aging diseases, rare in humans. There are a number of hypotheses as to why senescence occurs; for example, some posit it is programmed by gene expression changes, others that it is the cumulative damage caused by biological processes. Whether senescence as a biological process itself can be slowed down, halted or even reversed, is a subject of current scientific speculation and research.
