Big Brother is coming — to your wrist, forehead and ear. At least this Big Brother has your best interests at heart.
At this year's Consumer Electronics Show, vendors large and small introduced wearable tech designed to monitor your physical activities and biometrics and report the data to apps, websites and, if you like, your social media followers. Such devices already exist, of course — from Fitbit, Nike, Jawbone and others — but perhaps the wearable tech showcased here will proactively spur you to exercise. From wristbands to headbands to earbuds, there's something for everyone. (Except the couch potato).
