HOW IMPORTANT IS SEROTONIN?
Studies show that there is a chemical hierarchy in humans associated with social “rank” that is linked with serotonin levels. Those in high office, higher positions on sports teams and those of higher rank in academic clubs have been found to have higher levels of serotonin than their lower ranking peers. Low levels of serotonin are associated with depression, violent behavior and suicide. Many anti-depressants are designed to boost serotonin levels.
