The final lecture in this year’s series on age comes from Joseph Couglin, the head of MIT’s AgeLab, He famously remarked that raising life expectancy was “the greatest achievement in the history of mankind and all we can say is, is it going to bankrupt Medicare.”

In the following lecture, he talks about the need to change our conversation around aging and older people. The world’s fastest-growing market is also it’s most misunderstood. For decades, conventional myths have said that older adults simply want to age into a life of leisure. But defying conventions is what has defined this generation and Coughlin explains how we need to write a new story.
