progress sometimes comes in tiny steps. consider non-invasive glucose monitoring technology that is now available (the monitors have approval in europe but are awaiting fda clearance in the us). imagine the convenience this brings to diabetes patients who have to draw blood frequently to measure blood glucose levels. this opens the door to other kinds of non-invasive blood monitoring - will incumbent interests (that are invested hugely in blood testing) allow this major disruption to happen without a fight. i hope that good sense prevails...
