People's daily lives started becoming digital a decade ago. Now much of what everyone does is digitally recorded and acessible. This trend won't stop - and the benefits are astonishing. Based on their own research, Bell and Gemmell explain the ever-increasing access to electronic personal memories - both 'cloud' services such as Facebook and huge personal hard drives. Using Bell as a test case, the two digitally uploaded everything - photos, computer activity, biometrics - and explored the systems to best store them. The result is an amazing enhancement of human life.
