Even though life was harder in the past, but it seems that mental illness was not an issue to most families that requires authorities attention. Why mental illness is so prevalent these days? Has it existed all the times, or the way of life we live today is not compatible with our nature? Which is better for people's mental health: individualism or a strong sense of community? Was religion the psychologist/psychiatrist of the past to treat evilness/mental illness; that is, misunderstanding the human nature which was better for us?

Any thoughts?
