One-third of your life involves interaction with other people. Unfriendly behavior elicits unfriendly behavior. What are the consequences of your moods on your environment? And what are, ultimately, the consequences for yourself?

Your mood may be influenced such that you develop a depression. Antidepressant medications can then help. By stimulating serotonin, a chemical in the brain, they result in mood improvement. Furthermore, people who take a serotonin-enhancing drug behave in a more friendly way.  The same can be achieved by sufficient exposure to sunlight. This knowledge is important because your mental ánd physical health is significantly influenced by your social life.
