I have been saying for some time that the difference between being in your 50s rather than your 40s is that you go to the Dr and you don't expect to be cured. You are "managed" in your decline.I am in the middle of such a process. My haemoglobin levels are slowly declining and the cause is not immediately apparent.
Good on Dr Dave for persisting with me every six weeks or so for 30 mins (I was the first appointment and made him run late so early in the day). There are spectres that loom. Veiled references in conversation....if we don't find anything, don't imagine there is anything sinister (he said)....but then he doesn't say anything more and there is a sense that you feel he chose not to. Nothing sinister though.
