The Quantifiable You
Fitness trackers are increasing our access to personal data.

There’s Big Data and then there’s little data: the kind of small-scale, personal data we each can use to make better decisions about our daily lives. How to perform better at our jobs or during workouts. How to be more efficient.
Tracking everything, including your activity level, sleep quality and calories burned, wearable tech is giving us all expanded access to a better self. Experts say it’s a development that will move quickly from trend to every day — and play an increasing role in healthcare.
