Fitbit Flex Sleep Sensor Tracker

Will health sensors make humans immortal?

Not so fast! We need to get from here to there. Today, health/behavior monitoring and quantification sensors are all the rage. The Fitbit, a wearable sensor, is one of the more popular wearable tech devices for tracking your health. Fitbit tracks your activity (steps), diet, and even your sleep patterns. You can interact with the Fitbit using a series of tapping sequences and the Fitbit syncs all your data with your phone and computer. Then the process is to quantify, analyze, and optimize your wake and sleep life. Doing all this will not help you avoid your ultimate demise, but it could contribute to a longer life and better yet, one where you're in better health along your life's time-line. The concept is that if you are monitoring your activity, food, and sleep, you can make adjustments to improve these areas; thus better health. The Fitbit Flex is only $99!
