UnDisciplined: The Journalist And The Geneticist

David Sinclair is the author of a new book, "Lifespan: Why We Age - and Why We Don't Have To," which he wrote with the host of "UnDisciplined," Matthew LaPlante.

What if aging wasn't inevtiable? What if being 90 felt pretty much the same as being 40, just with a few extra decades of life experience? And what if the science that gets us to that point in human history wasn't the subject of speculative fiction — what if it was real? 

David Sinclair believes all of this — and more — may come to pass in our lifetimes. Before you pass this off as crazy talk, you should know this: Sinclair is a professor of genetics at Harvard Medical School and one of the most cited biological researchers in the world. 

He's also the author of a new book called "Lifespan: Why We Age — and Why We Don't Have To," which he wrote with our host, Matthew LaPlante. So today on UnDisciplined, we're bringing together a journalist and a geneticist for a conversation about aging, science, and how to communicate big ideas to a world that might not be ready.
