I was going to write that I'd achieved nothing all day but at 23:05 I managed to persuade my laptop and some new-to-me headphones (pre-unloved, I gather) to talk Bluetooth to each other.

Oh yes, and I listened to an All Party Parliamentary Group taking evidence on long covid and its possible effects on the NHS well into the future. Very interesting and very concerning. 
It's a completely unexpected bonus of this vile disease that some parliamentary activities now take place on Zoom and we the people can observe how politicians gather information to inform their decisions. (Well, some of them. I did note there were no Tories participating in this APPG.)
