Medical confusion

Got a phone call just now from the district nurses.  It's time for my annual flu jab she says.  I've never had a flu jab in my life.  She checks.  I'm not old enough.  Seems they start doing them when you're sixty.  Never did work out why she thought I was due.

Then she said that they have me down for a catheter change in January.  I have to point out that my catheter was removed when I had the prostate operation five weeks ago, and I phoned them when the operation was scheduled as I had been due for a catheter change that week.  Did manage to schedule the picking up of the spare catheter supplies I had left over.
