The longevity industry aims to let everyone enjoy a healthy, active life well past the age of 100. But the question everyone will be asking is... will it happen in my lifetime?

Manuela Saragosa reports from the Longevity Forum conference in London, where hundreds of researchers, investors, entrepreneurs and policymakers have gathered to try and answer this question.

Among them, she speaks to billionaire investor Jim Mellon; London Business School economist Andrew Scott; the youthful venture capitalist Laura Deming; Columbia University geriatrician Linda Fried; and cryonics fan Anders Sandberg of the Future of Humanity Institute.
