Researchers at Stanford University say with no porches in front and high fences in the back, we've become isolated in our homes. People are getting lost in it. It requires very little from them. They don't have to make eye contact. They don't have to give responses.
Psychologists warn that isolation is seductive, but that's because it's easy.
And it can get even worse. A rare few cut themselves off from friends, sometimes family, in order to just cope. What they end up with can be something dangerous to us all. Or Ted Kaczynski, the unabomber. Add a deluge of media images like the ones that that mesmerized John Hinckley and you get still more problems.
