Background: When animals lick mineral salts, the salts and trace elements enter their bodies, connecting the natural cyclical systems within and outside their bodies. The heartbeat propels not just the body fluids but also the transport of inorganic substances. Humans too continuously perceive and exchange these substances with their bodies and minds. A paper by researchers at the 306th Hospital of the People's Liberation Army, titled "The Relationship Between Healthy Cardiovascular Autonomic Nervous Function and Trace Elements," indicates that the concentration of trace elements such as manganese, lead, and aluminum is closely related to the function of cardiovascular autonomic nerves. Trace elements like manganese and lead can affect the stability of heart rate variability (HRV) and subsequently impact cardiovascular autonomic nervous function. These elements also have various impacts on neurobehavioral functions. Excessive intake, deficiency, imbalance, or lack of trace elements can cause varying degrees of abnormality and disease in the body.

Operation:

1. A heap of naturally shaped Himalayan mineral salt is piled up. Some salt blocks are carved into the shape of animal hearts.

2. An opening is made at the arterial end of the heart, and a light bulb is installed, which is programmed to flash at a rhythm close to the human heartbeat.

3. In another set, a series of heart sculptures are interconnected by plastic tubes filled with a blood-red liquid, creating a circulatory system driven by a peristaltic pump.
