In addition, there is a reverse mechanism through which the health status of a population affects longevity or life expectancy, which, in turn effects economic growth and further increase longevity, which, in turn, induces agents to spend more on capital investments, which in turn affects economic growth. . In other words, the health status of the population, population growth, population longevity, and economic investment are all interacting variables in a dynamic system (model) which undergoes a phase transition at various thresholds. The theory predicts three basic models, each of which is charact
