We examined statistical life expectancy, actual causes of death, and problems of statistical models, and found that statistical life expectancy is irrelevant to specific persons and has little utilities for estimating and extending lifespans and health spans for specific persons. To provide a model for extending human lifespans and health spans, we propose “usable organ capacity” for individual persons as a measure of lifespans and health spans. We show that personal lifespans and health spans depend on organ’s biological potential, maximum usable organ capacity, decline rate of usable organ c ..read more

Having proved flaws in using clinical trials to study weak factors, we want to investigate how life factors affect health and diseases. In this study, we show that cancer, heart disease and infectious diseases are inherently preventable and curable. We would like to find how life factors revolving around environment, emotion, activity, disease agents, diets, behaviors, etc. affect disease outcomes. We expand the scope of the immune functions to include functions for removing garbage and repairing tissue damages, and then identify six classes of health properties for evaluating the immune syste ..read more

We examined special roles of the Central Nervous System (CNS) in an attempt to resolve the puzzle that chronic diseases cannot be cured by medicine. By exploring a skill-learning model, we found that the CNS is able to remember certain information reflecting biochemical and cellular (B&C) processes in the body. From the skill using ability, we found that the CNS is able to control basic B&C processes that drive and power the skill. From the ability to adjust forces and force direction of a physical act, we found that the CNS is able to adjust B&C processes that drive the physical a ..read more
