Emerging science has identified a critical player in the science of aging—inflammation, which is suspected to contribute to the process. A little-known blood marker called CHIP (clonal hematopoiesis of indeterminate potential) is one way to measure the problem.

According to Salvatore Viscomi, M.D., chief medical officer of GoodCell, some of humanity's most common diseases are driven by an inflammatory condition called clonal hematopoiesis, a fancy term for the replication of mutated cells in the blood or bone marrow. Too many mutations lead to diseases we used to brush off as normal byproducts of "aging." Fortunately, it's now possible to measure the extent of clonal hematopoiesis using a blood marker called CHIP. Although CHIP is still relatively unknown, some people see it as a game-changer in the world of
