The Times has a short ditty warning of the dangers of modern electronics and pacemakers, ending up with an unintentional 'chuckle at the unfortunate elderly' piece, including the story of a man whose use of an 'alternative medicine' device called the Zapper (dude!) would stop his pacemaker until he fainted and dropped the device. Unfortunately, it took the patient several months to discover the error. A tip: If you have a pacemaker, do not run electrical current through your body. This is science fact. It's good that research is being done on pacemaker safety, despite the opportunity for geriatric hilarity. In a few short decades almost everyone will be sporting implanted electronics, and it would be nice to know how to avoid knocking ourselves unconscious.
