MRI trauma

My husband got a routine MRI this week and reported considerable annoyance at the number of times he was forced to answer the same questions about whether he had any metal implants. I like this radiological imaging center, but they do indulge in some repetitive questioning. Before they even got a chance to pepper him with inquiries, they'd already made me answer the same questions at length when I called to make his appointment.

Then a story like this comes along and makes you imagine how obsessed they must get with checking and re-checking and practically guarding the doors to make sure no one wanders in unawares. Those magnets are unbelievably strong.

John Ringo wrote an entertaining novel called "Von Neuman's War" about a attack by alien bots bent on stripping metal out of people and machines. Earth's citizens had to get serious about tooth fillings, braces, and medical implants.
