Too many of the elderly do not have the family or the communal attachments necessary to feel valued; too many are widowed or otherwise alone; too many live in surroundings where they are essentially without the companionship necessary to stimulate a mind in danger of deteriorating. Too many are so poor or unable to obtain social services that they cannot remain in their own homes, and are certainly without the wherewithal to live in an upscale retirement community or assisted-living facility. Too many have passed their entire lives without the level of education and general knowledge necessary to take advantage of what is available to their peers raised in circumstances of greater awareness. For the vast majority of such men and women, so often socially and even physically more or less isolated, modern gerontology and its discoveries might as well not exist.
