What are we all gaining — or losing — by reducing the mundane moments of our lives to a bunch of numbers and graphs?

How We Got Here

It's easy to think that this whole "life by the numbers" concept is a new phenomenon, but that notion simply isn't true. People's fascination with personal metrics predates the modern digital age.

Pedometers rose to popularity in the '60s, offering a basic way to keep up with steps for health purposes. In the '70s, the first wearable sensors with wireless…
