Catheter tube managed to get a bit twisted yesterday- that wasn't a lot of fun! Still, major disaster has been averted

I'm noticing just how tired any little bit of walking/exercise is making me - I guess that's no great surprise, given what the body's just gone through. You do feel like a little old lady creeping along the corridor and waving at the nurses as they sit at their station.
For those of an older generation I'm put in mind of "'young' Mr Grace" from "Are you being served" and his "you've all done very well" catchphrase, before he had to be whisked away by his young assistants. OK, maybe not quite so much like that.
