While this may be true to a point, some people prefer to be alone and do quite well, live long and prosper.
People that are comfortable with themselves, their thoughts, and can see the wonder in everyday things, everyday, natural or not, do not seem to get "lonely"; at least not like those that must have a TV, radio, and/or some other noise at all times, even just to sleep, if they are not engaged in a crowded room full of people along with the nonsensical banter.
That said, i would be curious to find out whether this affects females more than it does males... I bet it does.
