Yeah, well, that's just lovely. So if my results come back as >5 rather than the coveted <5, how will that affect my belief that I will survive/live to a ripe old age? That belief is important. Hope is important.
All of these tests are so double-edged. I try to weigh the advantages/disadvantages of having them, of hearing the "predictions" that are based on them. They say that we humans are startlingly responsive to the power of suggestion. Some claim that patients would be better off if they never heard the predictions that go hand-in-hand with the test results, that what we don't know is less likely to hurt us (because we are so susceptible to the authoritative voices of the doctors and the system).
I can see both sides of it. On the one hand, I don't want to feel that I am sticking my head in the sand, refusing to hear "the reality." Being in denial. On the other hand, what if I am placing too much value on that supposed "reality?" What if that reality isn't really reality but just another highly fallible tool developed by highly fallible humans who are doing the best they can but are unable to see that test results do not a whole picture make.
