Vincent van Gogh ate yellow paint, because he believed that this would contribute to his happiness from the inside. Because of this act, many people thought he was crazy and stupid because the paint was toxic, and it was obvious that the use of paint could not have any direct interaction with someone's happiness, but I never thought so. If you were so unhappy that even the most crazy ideas could possibly work, for example, drawing yellow on your walls of internal organs, then you would do this too.
