The truth is that I sometimes forget that there are quite a number of people – all friends – who read my blog, so I have been grateful for so many kind messages from all over the world including this morning from Tasmania and Japan.

It is possible that someone from the NHS reads it as well because not long after my last post I got a very helpful call from the Covid Unit at Mile End Hospital where we are going this morning. So the system does work, if sometimes a bit creakily.
