The World Health Organization projects that the world's population of older adults will double by the year 2050 and 80 percent of these older people will be living in low- and middle-income countries. Preparing for this shift – known as population aging – needs to start now. Dr. June McKoy, a Northwestern Medicine Geriatric Medicine Specialist, joins Dr. Rob Murphy on this episode to talk about this phenomenon and what students and trainees need to know to address the needs of older people here in the U.S. and around the world.
