How’s your health? How can you tell. There are all kinds of devices that you can buy that can help you answer that question. A simple blood pressure cuff can tell you a lot. The new watches can read your pulse and track your activity. In the future will Doctors even be needed. Will we just load out symptoms into a data base and be diagnosed right at home. Will the sensors we have attached to our bodies eventually make changes to out body t correct problems. Can the sensor tell a insulin pump how much to pump? Joe Olujic is optimistic bout all this.
