Using wireless insulin pump.
I am an Electrical and Electronics Engeneer with specialization in computers and RF communication.
I don't believe that anybody (McAfee employee or Al-Kaida terrorist) can possibly access my insulin pump or my Glucometer.
My insulin pump can deliver 315 units of insulin in one go, without triggering any alert, if programmed or operated to do so.
I use ~41 units of insulin per a day. It is 7 days, 16 hours and ~ 20 minutes of insulin. It is ~17% of 45 days.
I am not worried, it is just a regular pile of FUD.
