Breakthroughs in medicine and science have nearly doubled life expectancy in developed countries since the 20th century. While many view that as a positive, others see it as a burden - on finances, health care, and even society.

Dr. Linda Fried, dean of the Mailman School of Public Health at Columbia University and senior vice president of Columbia University Medical Center, will join The Daily Circuit Tuesday.

"Most young people, in fact, most middle aged people can't imagine being 70 or 80 or 90 years of age," she told The New York Times. "At this moment of human history do we know how to become a population of longer lives of older age? Do we know how to step into this unknown and do it well?"

Dr. James Pacala, associate head of the University of Minnesota Department of Family Medicine and Community Health and president of the American Geriatrics Society, will also join the discussion.

"We don't really have a national plan on how we're going to be able to care for everybody and the burden of disability that we are going to be faced with in the next few decades," he said on PBS.

And as those numbers of disabled people grow I'm not sure that we've really figured out what we are going to do about it. We need to have a better approach."
