The Internet of Things ... for the human body?

You wake up in the morning and glance at your phone. In an app, you see your blood-sugar level, your exact heart rate, your metabolic rate, and your calorie count. But how is this possible? In the future, the Internet of Things (or IoT) will invade the human body. Gadgets from companies like FitBit and Misfit can already track your heart-rate in real-time. You can step on a wirelessly-connected scale and send the results to an app. For fitness nuts, these gadgets help you track progress during a workout or lose a few pounds.
