Wi-fi devices implanted in a human body could be used to warn doctors in the event of a health emergency, but the concept raises questions.
The device could, using Bluetooth, sense a problem in a person like a heart attack or diabetic complication and contact a doctor through a base station in the patient's home.
It would also be a great way for the robots to remotely shut down some hearts. Faster medical response is great, but at what cost?
