Bill Barol here, the producer of HOME. This is an episode about Andy Puddicombe, who left college at 22 and spent a decade tramping the world before returning to the UK and landing, eventually, in Los Angeles, where he leads the meditation platform Headspace.com. He’s lived in so many countries that he has trouble recalling them on demand. How did his travels, and his training in Buddhism, alter the way he thought about home?
