Well bored today read an article where a chip implant that can detect swine flu, and also can be used for other viruses has been unveiled today by verichip ( who created the infamous rfid implant).
As you read it would appear the founders have more scope to the project, eventually linking health records, insurers, employers and more.
This is all very sci fi, and tbh a little scary, what (if this is implicated and addopted ) could this mean. ''Sorry sir, you cant have the pizza, it would appear your doctor wont allow it, as you have hi blood pressure''
