Most would not last very long I agree. But I don't think that those that find the hermit existence more to their liking (and can sustain such an existence for an extended period of time) would "come crawling back" or anything like that. Once my kid is out of the house, I don't really care about not kicking the bucket a little sooner if by doing so I could live out my last decade or two in peace and without having to deal with the daily stream of bovine manure that "civilization" entails.
