Loneliness is deadly:
http://www.slate.com/articles/health_and_science/medical_exa...The "epidemic of loneliness" has spread to many places. If you haven't read "The Lonely American" I implore you to do so if you care about this topic at all. An incredibly sobering read.
Book blurb:
"In today's world, it is more acceptable to be depressed than to be lonely-yet loneliness appears to be the inevitable byproduct of our frenetic contemporary lifestyle. According to the 2004 General Social Survey, one out of four Americans talked to no one about something of importance to them during the last six months. Another remarkable fact emerged from the 2000 U.S. Census: more people are living alone today than at any point in the country's history—fully 25 percent of households consist of one person only.
In The Lonely American, cutting-edge research on the physiological and cognitive effects of social exclusion and emerging work in the neurobiology of attachment uncover startling, sobering ripple effects of loneliness in areas as varied as physical health, children's emotional problems, substance abuse, and even global warming. Surprising new studies tell a grim truth about social isolation: being disconnected diminishes happiness, health, and longevity; increases aggression; and correlates with increasing rates of violent crime. Loneliness doesn't apply simply to single people, either—today's busy parents 'cocoon' themselves by devoting most of their non-work hours to children, leaving little time for friends, and other forms of social contact, and unhealthily relying on the marriage to fulfill all social needs."
