The Quantified Self Movement
New consumer technologies are making it possible to build data-rich profiles of your body and its day-to-day and minute-to-minute operation. Smartphone apps allow you to track your jogging routes and speed. Smart watches and other gizmos, like Fitbit, Jawbone and the Basis watch, compile detailed information about sleep patterns, heart rate and the number of steps you take each day. Tech Tuesday explores the "quantified self," a movement to harness personal data to increase healthy living.
