All five sons have liver disease. Is it a matter of ancestral graves and geomantic omen?

The liver is the largest digestive gland in human organs, which has important functions such as secreting bile, storing liver glycogen, synthesizing protein and excluding endogenous or exogenous substances. All five sons have it. From a scientific point of view, it has nothing to do with ancestral feng shui. This is a superstitious statement, which may be caused by heredity and gene mutation.
