A young seemingly healthy medical journalist for the purpose of writing a review of the latest piece of scanning equipment decided what better way to do it than to test it on himself. The result unexpectedly revealed tiny nodules which would otherwise have gone unnoticed for years , if ever. A few years later he finally received the all clear. Unfortunately he was by then an emotional and financial wreck. I am an AF sufferer . I can't help thinking of that unfortunate journalist when reading some of your posts. Too much knowledge?
