What is the difference between physiological and chronological age?
Things to know from topic 2:
List the general functions and characteristics of Catecholamines (Epinephrine/Adrenaline and Norepinephrine/Nonadrenaline)
List some differences between the hunter-gatherer and modern man.

Hunter-gatherers ate a variety of plants and whole animals(wild animals=relatively low fat, high in "omega" fatty acids), high fiber, calcium, magnesium and potassium, low in energy density and glycemic load, and performed 3-5 hours of physical activity per day.
Cars, kitchen appliances, remote controls, elevators, refined grains in their natural form, meats are "marbled" and therefore higher in fat.
Secreted from the adrenal medulla (the adrenal gland is a small organ thsat sits on top of the kidney); also released as neurotransmitters by the sympathetic nervous system (SNS); increase heart rate and heart muscle contraction force; control several aspects of blood flow to tissues (for example, increases skeletal muscle blood flow); stimulate glycogen breakdown in muscle and lipolysis (fat breakdown) in adipose tissue (fat cells); decrease at a given absolute intensity with exercise training.
Protective polymorphisms are expressed when one consumes fruits, vegetables, whole grains, and exercises, while susceptibility polymorphisms do not get activated. Susceptibility polymorphisms are activated when exposed to a typical American diet, physical inactivity and the use of tobacco products.
True
Physiological age refers to the amount of stress placed on the body, while chronological age refers to how many years one has been living.
Gene activation(how it works), protein synthesis, quality of life vs. lifespan and the effects of environmental factors on the two.
