According to the U.S. Census Bureau, the country’s population aged 65 and over is projected to be more than 83 million in 2050 — almost double the estimated population of 43 million in 2012. This Forum examined how the growing, greying labor force impacts workplaces and economic and health security, including retirement savings efforts and systems such as Social Security and Medicare. The discussion also explored what it means to age productively and healthily, with a particular emphasis on the value of working, volunteering and keeping cognitive skills sharp. Presented February 11, 2016 in Collaboration with The Huffington Post. Watch the entire series from The Forum at Harvard T.H. Chan School of Public Health at www.ForumHSPH.org.
