Keyboard three fixed
I had to completely disassemble the keyboard, but the whole job - dissassembly and reassembly only took two hours. The problem was as I thought, the spring assembly for the U key wasn't moving freely, there was a bit of plastic scurf blocking it.
When I tested it, the right hand ctrl key didn't work, but I don't use that key, I always use the left hand ctrl key. Because it's either ctrl-c or ctrl-v. So am I bovvered?
But after fiddling with it for a bit, I think I got it working. Anyway, job done. And this was the keyboard that I thought was most likely to be unfixable!
Now the fourth ...
I also paid a routine visit to Amersham hospital, to have an INR test. My INR was 2.4, and the ideal range is 2.5 to 3.2. It has been wobbling about a bit, and they've been chasing it around. So now instead of 6.5 mg per day, I'm on 6.5 per day and 7 on weekends. Which is 6.64, a whole 0.14 milligrams more than before, a 2% change.
While I was there, I toddled over to the blood test clinic, this is part of the investigation into why my liver ALS is so high. It isn't booze; most weeks I have none, some weeks I might have a bottle of beer.
They saw me immediately, took a couple of vials of blood out of my arm, gave me a bit of cotton wool, and I was done.
So I visited the bookshop on my way out, and treated myself to four books, while at the same time helping the scanner fund.
Then, fours hours later, I went back for my ultrasound scan. I lay on my back while a nice nurse tickled me and eventually told me that she'd found nothing of interest. So I bought four more books. This is why paper books are better than e-books. I can buy second-hand paper books.
