eurekalert.org (07.12.2022)  The success of longevity interventions is putting countries on paths to becoming aging societies, in which the number of individuals aged 65 and older is equal to the number of people aged 15 and younger. This outcome may lead to resistance to investments in healthy longevity, according to aging experts, if concerns are raised that the needs of older individuals will overwhelm societies, exacerbate ageism, and divide populations. The National Academy of Medicine in the United States addressed this possibility as its first-ever Grand Challenge, and in June 2022 published the Global Roadmap for Healthy Longevity, developed by an independent and interdisciplinary global commission co-chaired by Linda P. Fried, MD, MPH, dean of Columbia University Mailman School of Public Health and John Eu-Li Wong, Isabel Chan Professor in Medical Sciences and senior vice president of health innovation and translation at the National University of Singapore. A commentary in the Dec. 2, 2022  Nature Aging, by Dr. Fried, Dr. Wong, and Victor J. Dzau, MD, president of the National Academy of Medicine, reviews the findings and recommendations of the Global Roadmap.
