The people you see talking into their Bluetooth cell phone devices in the store can be distracting, but the London Times reports that the technology could be a lifesaver.

Bluetooth says doctors could implant patients with devices that run on the same technology as Wi-Fi.

A "Bluetooth regulator" could be used in pacemakers and alert a hospital if someone is at risk of having a heart attack.

Health experts say they are skeptical about these in-body sensors, and they're looking into the possible radiation risks.
