Why so lonely? : }

In this CNN article, a group of researchers was able to determine loneliness may be affected by genetics. After 8000 twin and sibling cases, they have found strong evidence to support this case. They explain that much of this is probably caused by evolutionary psychology. Our ancestors stayed in groups to protect each other from predators, therefore we feel lonely when we're isolated from each other as a biological defense mechanism. I agree this could be part of the problem, but it doesn't really account for our varying tolerance for isolation between people. The article goes further to explain that a good way to avoid loneliness is to participate in community service, much like how we do in NHS :D
