Adjusting Biomechanical Mechanisms to Extend Life

The Longevity Dividend model seeks to prevent or delay the root causes of disease and disability by attacking the one main risk factor for them all—biological aging. Evidence in models ranging from invertebrates to mammals suggests that all living things have biochemical mechanisms influencing how quickly they age, and these mechanisms are adjustable. It is possible—by dietary intervention or genetic alteration—to extend life span and postpone aging-related diseases such as cancer, cataracts, cognitive decline and autoimmune diseases.
