Dr. Linda Fried illuminates aging research by Marilynn Larkin, MA

"We’ve added 30 years to human life expectancy [over the past century], in part through intentional human investment, including through science," says geriatrician and epidemiologist Linda P. Fried, MD, MPH, dean of the Mailman School of Public Health at New York’s Columbia University. "We’ve also demonstrated that many of our expectations about those 30 years, such as ‘They’ll be a disaster,’ don’t have to be true." ... Fried states, "The purpose of research and science is to have a formal process to pose the big questions that could lead to a better future--questions that matter, but to which we don’t know the answers."
