Allostatic Load refers to the physiological costs of chronic exposure to many organ systems to stress overload. It is used to explain how frequent activation of the body's stress response, an essential tool for managing acute threats, can in fact damage organ systems in the long run. To measure this accumulative wear and tear, a composite index of specific biomarker/metrics of cumulative strain on organ systems would be tested using blood samples. We have identified several of these biomarkers/metric that can measure health trajectory. In addition to the annual physicals, as an adjunct, would you take the test?
