CT SCANS
Thinking of a full body scan? think again, and save your life. A CT (computed tomography) scan will expose you to radiation equal to that from the atom bombs dropped on Nagasaki and Hiroshima . Not only will they zap you with enough radiation to significantly shorten your life, but they aren't even much chop.
According to the Journal of the American Medical Association, they have "long been controversial because of uncertainties surrounding their ability to detect hidden disease."
My advice: Eat well and avoid illness and shun fancy, expensive and dangerous diagnostic equipment.
