Most+simple+and+fundamental+way+to+improve+people's+health+9-12-12

I think that one way to improve people's health would be to make them aware of the most simple and fundamental aspects related to health. Right now I would like to argue that if people were aware of how hydrated they are, how the health of their cardiovascular system is, how thin or thick their blood is, and how biomarkers related to stress and inflammation are fluctuating then I think many people would naturally modify their behavior to improve these biomarkers. For example, they may eat more hydrating foods and engage in appropriate types of physical activity. I would like to note that in the book The Biology of Human Longevity he points out that people have not been able to identify extremely good biomarkers that can predict lifespan. One of the best determinants of lifespan identified so far appears to be cardiovascular health measured by things like systolic blood pressure.
