TED Talks Daily (SD video)

TED is a nonprofit devoted to ideas worth spreading. On this video feed, you'll find TED Talks to inspire, intrigue and stir the imagination from some of the world's leading thinkers and doers, speaking from the stage at TED conferences, TEDx events and partner events around the world. This podcast is also available in high-def video and audio-only formats.

It's never too late to reinvent yourself. Take it from Paul Tasner -- after working continuously for other people for 40 years, he founded his own start-up at age 66, pairing his idea for a business with his experience and passion. And he's not alone. As he shares in this short, funny and inspirational talk, seniors are increasingly indulging their entrepreneurial instincts -- and seeing great success.

"From populist demagogues, we will learn the indispensability of democracy," says novelist Elif Shafak. "From isolationists, we will learn the need for global solidarity. And from tribalists, we will learn the beauty of cosmopolitanism." A native of Turkey, Shafak has experienced firsthand the devastation that a loss of diversity can bring -- and she knows the revolutionary power of plurality in response to authoritarianism. In this passionate, personal talk, she reminds us that there are no binaries, in politics, emotions and our identities. "One should never, ever remain silent for fear of complexity," Shafak says.

We've all heard that robots are going to take our jobs -- but what can we do about it? Innovation expert David Lee says that we should start designing jobs that unlock our hidden talents and passions -- the things we spend our weekends doing -- to keep us relevant in the age of robotics. "Start asking people what problems they're inspired to solve and what talents they want to bring to work," Lee says. "When you invite people to be more, they can amaze us with how much more they can be."

Sara Menker quit a career in commodities trading to figure out how the global value chain of agriculture works. Her discoveries have led to some startling predictions: "We could have a tipping point in global food and agriculture if surging demand surpasses the agricultural system's structural capacity to produce food," she says. "People could starve and governments may fall." Menker's models predict that this scenario could happen in a decade -- that the world could be short 214 trillion calories per year by 2027. She offers a vision of this impossible world as well as some steps we can take today to avoid it.

In this important talk about mental health, she speaks openly about her struggle -- and why communities of color must undo the stigma that misreads depression as a weakness and keeps sufferers from getting help.
