Given the number of people who commented here with their own stories I wonder if it actually is rare.

I imagine you only find out if you're undergoing x-rays, operations and similar.

If there are no obvious side-effects there could be a lot more flipped-people out there.

Doesn't almost everybody receive x-ray, ultrasonography, abdominal palpation, stethoscopy, ECG or surgery today? Does it happen often that a person grows up never ever examined by a doctor closely?
