Over the last hundred years, mental health professionals have told us that depression is caused by a chemical imbalance in the brain. However, there is a much more realistic theory that depression occurs due to an imbalance that occurs outside of your skull. New York Times journalist Johan Hari believes that depression these days comes from social problems. Johann offers some amazing statistics that show that antidepressants seem to be doing far more harm than good, including that one in four men in the United States is taking a chemical antidepressant in a given year. If we want to get rid of the modern depression, he says, we have to change society.
