Its like when I went for a broken tooth... The dentist insisted on a panoramic xray of my head/jaw... Then he came back and said: yep you have a broken/chipped tooth... And the funny thing is that he protected my chest from the xray with a lead cover but not my brain... And the tooth broke because it was repaired from a previous cavity
