The key components of health are nutrition and stress management. Nutrition is addressed elsewhere and stress management mostly involves simplifying your life style. Medical science cannot heal anyone. They can assist the body in healing itself, but they totally ignore the reality of true healing done by the power of God. This is more available then people realize and thus is not even sought. This kind of healing does not eliminate a need for medical professionals, They have a place, but it is much reduced from the current system.
