Some of the world’s brightest minds convened at the Milken Institute Global Conference last week.

One panel discussion, titled How Increasing Longevity Will Shape Our World, was especially interesting; watch the discussion in the video above.

The panelists — including Mark Freedman, founder and CEO of Encore.org; Dr. Linda Fried, Dean of Columbia University’s Mailman School of Public Health; and others — discussed the issues, challenges and opportunities posed by an aging world in which 1 of 3 Americans are over 50 years old.
