People are in varying states of health. Some folks are in optimal health with vitality and others are in a stage of disease. Most, are in between stages of health. They are either repairing and gaining on their health or moving closer to symptoms of disease. We are either in the process of degenerating or regenerating. Anabolism or catabolism. Health is not static, so where you are on the health spectrum dictates your requirements for exercise, nutrients, sleep and maybe even supplementation or medication.
