Aging is the main risk factor for virtually all chronic diseases affecting humankind. Geroscience is a relatively new field that, by addressing that fact, posits that clinically addressing the biology of aging will have a much larger impact on human health than the current approach of addressing diseases one at a time. In fact, aging biology research has advanced to the point that a level of understanding has been reached where a geroscience-focused approach to medicine appears not only feasible, but necessary.
