Life expectancy has been increasing over the years, and so has the longevity business. WSJ health and wellness reporter Alex Janin tells WSJ’s Charlotte Gartenberg about the booming business of extending our healthy years and our lives overall.

WSJ health and science reporter Amy Dockser Marcus looks at the debate over the limits to longevity and finds that, no matter the hype, some scientists think you won’t live to 100.
