(CNN) -- America is facing the greatest health care challenges in its history. Unprecedented demand is a certainty. According to the Department of Health and Human Services' Administration on Aging and U.S. Census Bureau statistics, the number of Americans 65 and older has exploded by a full 6 million in the past decade to over 13% of the overall population, while the population of "oldest old" -- those 85 and older -- has increased by a factor of 10 from the 1950s to today's 6 million. Older people harbor the most disabling diseases, including heart disease, cancer, stroke and dementia: the diseases that depend most on specialist care and complex technology for diagnosis, management and treatment.
