Live to 150? David Sinclair on why we age — and why he thinks we don't have to

What if we could turn back time on our biological clock and slow down — even reverse — aging? High profile Harvard scientist David Sinclair is co-author of the New York Times bestseller Lifespan: Why We Age and Why We Don’t Have To. His lab’s work is as ambitious as it is controversial. He wants to radically change the way we live our lives — and push at the boundary of what it means to be human.
