UnDisciplined: The journalist and the geneticist

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.
