Many measures that may extend lifespans may simultaneously also extend healthspans, albeit that is not necessarily the case, indicating that "lifespan can no longer be the sole parameter of interest" in related research. While recent life expectancy increases were not followed by "parallel" healthspan expansion, awareness of the concept and issues of healthspan lags as of 2017. Scientists have noted that "[c]hronic diseases of aging are increasing and are inflicting untold costs on human quality of life".
