Do meditation apps really work?

Headspace CEO Rich Pierson talks with Kara Swisher and Lauren Goode about meditation apps and why it's important to find stressed out people where they already are — on their phones. Pierson says people used to back away from him and his co-founder when they learned about the company, but the world is coming around to the idea of guided meditation as a valid way to improve one's mental wellness. He also explains why meditating can sometimes make you angrier or, at least, more aware of how angry you already were. Plus: Kara shares her own not-so-zen, and decidedly morbid, meditation regimen.
