Aspen Lecture featuring Laura Carstensen, Fairleigh Dickinson Professor in Public Policy, Department of Psychology, Stanford University; Director, Stanford Center on Longevity. We are approaching a watershed moment in human history; a time when old people outnumber children and living to 100 is commonplace. There are major challenges associated with this dramatic and sudden increase in life expectancy, yet, Carstensen says we must not lose sight of the fact that long life presents unprecedented opportunities. If we use science and technology to solve problems associated with aging and we develop new social norms and lifestyles, she asserts that the entire life course can be redesigned in ways that dramatically improve quality of life at all ages. The Aspen Lecture convene some of the world's greatest minds in an interdisciplinary series that explores topics ranging from the Big Bang to representative democracy to Shakespeare.
