Amazing new tech! This has got to be the way medicine is going. how exciting imagine the amount of data that will be generated over the next few years with fitness apps and noninvasive blood work. Imagine what we will learn, how it will help us detect cancer! As long as it remains subtle and non intrusive. I don’t want apps telling me how to live my life, and alerting me to when I need to eat what, but I wouldn’t mind a few guidelines and a bit of advice.
