Health management system
The health management system (HMS) is an evolutionary medicine regulative process proposed by Nicholas Humphrey in which actuarial assessment of fitness and economic-type cost–benefit analysis determine the body's regulation of its physiology and health. The incorporation of the cost–benefit calculations into body regulation provides a science grounded approach to mind–body phenomena such as placebos, are otherwise not explainable by low level, noneconomic, and purely feedback based homeostatic or allostatic theories.
