What is health

• Each human can be considered to be a unique biological system.
• Health is defined as a state of complete physical, mental, and social well-being
• Even with 99.9% similarities in humans, there is extreme variation that is how race came into play.
• The Control and Communication network (CCN) coordinates the functions of a person using: central nervous system, peripheral nervous system, endocrine system, local support and defense system
• Many diseases stem from diminished or abnormal functions of the CCN
• Aging reduces the function of the CCN
• Psoriasis is a skin diseas where the epidermis cells are affected. The keratinocytes proliferate at 10 times the rate of normal skin.
• Scaling on the dimension of time can be done through a) growth, development and aging b) maintenance and repair c) homeostasis and d) action potentials and enzyme catalysis
• Many factors affect healthspan. Once someone's healthspan starts to deteriorate they will become more and more dependant until they die
• Biomarkers are an assesment of status of health over time that can be measured objectively
• Circadian rhythm (diurnal variation) coordinates almost all of the body's psycological needs and functions.
• Bone density is one of the best biomarkes of aging. It can predict the risk of osteoporosis due to the quantity of calcium in the bones.
