I guess even cardiac surgeons will err on the side of caution when presented with unclear data. My father, ever pragmatic, looks at it this way: Hell... I'd rather he be concerned and give me a test that turns out to be unnecessary than overlook it and I blow the goddamn thing when I'm out tossing hay bales in the stable. This way I'm only slighy inconvenienced. The other way? I'd be dead.
Too true, Dad.
You never count your money when you're sittin' at the table.
