Blood Currency Prosperity
Blood flows through the Human Heart in one direction. Check valves keep the flow of blood going in one direction. In and Out the blood flows so long as the check valves keep working. If the check valves do not do the job, then, blood stops flowing. Check valves control the direction of flow. Blood flows one way and blood does not flow the other way. A check valve is like a one way street.
Blood flows like the current in a river, like direct current in electric circuits, like current news, and like monetary currency in economic human Markets. Currency flows through human life in many forms. Check valves work in many forms.
Gravity works as a check valve in the circuits where rivers flow; water goes down when in liquid form and water goes up when water is in the form of a gas. Gravity is the check valve controlling the flow of water in our global ecosystem.
Check valves exist in electric circuits. More on that later.
Check valves control the flow of current news too. Each person receives current news and passes on the news or rejects the current news. The flow of current news is much more like AC electric current. DC electric current has a built in check valve. More on that later.
Check valves control monetary currency too. One such check valve is called interest. Interest is very interesting.
Looking at some charts may help illuminate the relationship.
