Do you know "The Death of Zhou Yu" in the Three Kingdoms? If not, I would like to summarize in a sentence: "Zhou Yu envied Kongming so much that he coughed blood and died." Death by envy? You might laugh at it and say that it's nonsense, no one dies of envy. If you are too envy of others and cannot express it with anyone or a squad to insult the better one, you must be unable to sleep or eat well because that person keeps on showing off their promotion or a big house or a cool vehicle... Sooner or later, you will "fall ill and die".
