> People only turn yellow if they have kidney or liver damage.
This is not true. Roughly 5% of people have Gilbert's Syndrome which is genetic, metabolic abnormality where the bilirubin from dead blood cells are conjugated slower than the baseline patient leading to yellowing of the skin. It is not due to liver damage or disease and is a benign condition. Not to mention there is carotenemia from eating too many carrots or squash -- again not kidney/liver damage related.
Gilbert's Syndrome is a genetic disorder that causes liver malfunction, and people can't produce proper enzymes.
This thread discusses physiology in an art context. Maybe get outside for a walk, and consider if LLMs are making people silly. =3
