Yes, now that I know about Paxlovid, I will invoke it by the power of the NHS if I get Covid again, though one doesn't hear of it as a common option here. Your advice is wise, thanks for it, as always.

As for all those to-do lists...I like to think of them as structural help for making me feel good about what I have done in a day. But they're all collapsing, so I may as well sit back and enjoy the panettone :-)
