It is a medically acceptable term for laziness!
I have not been too well for a few days, and though some of my colleagues have brought the odd bug to work in the last week or two, my symptoms don’t precisely fit with theirs. I went home early on Thursday with a headache and feeling a bit wonky (another medical term), and by Friday I was feeling worse, with bad headaches and muscular pain, loss of appetite, thirst,
exhaustion and weird dreams. And then a bleeding nose, something I have not had for years. Saturday I felt like a zombie. On Friday and Saturday night I actually slept under a duvet! Today, despite it being a fairly cool rainy day, I am drenched in sweat, but otherwise feeling a little better, though still with the headache. So. Doctor tomorrow. I suspect blood pressure may be involved, either as a symptom or a cause.
I really wanted to get out in the kayak this weekend, and almost set off earlier this morning, but the lassitude beat me. Maybe just as well.
