Life is systems activity
A system is a network of channel flows
Circulation is flow
The heart is a circulatory pump
Muscles pump organic fluids
Cells pump organic fluids
A sponge is a pump
Organic bodies are a sponge.
A pump is an iterative function, absorbing inputs and excreting outputs
A chain of iterative functions form a network of channel flows
Health is a function of a systems ability to pump organic fluids, thereby circulating and transporting the building blocks of life for energy and repair
Activity that pumps fluids improves health by increasing biological activity
Fasting refreshes and cleanses biological pumps.
Improve biological pumps, and you improve circulation, and health.
