Psychologist Susan Blackmore investigates how we are outsourcing the memory of our lives to digital devices and asks whether that is changing the nature of human memory.
She hears from a ‘lifelogger’ who is recording every detail of his daily life - and from an academic who has taped 220,000 hours of audio and video of his infant son. Susan asks whether we will all end up doing the same and how this will affect the way we remember our own lives.
