Do you say that on basis having yourself been a patient at St Thomas', or any other large NHS hospital, in an intensive care ward or elsewhere, or do you have friends who work there, or what?
It might be his rhetorical style or some other misunderstanding on my part, but my suspicion was based on what he said.
In particular, he thanks "two nurses who stood by my bedside for 48 hours when things could have gone either way ... who for every second of the night, they were watching." He thanks many other people as well and goes on to say that on the basis of his experience, the experience of a Prime Ministerl, "that is how I also know that across this country, 24 hours a day, for every second of every hour, there are hundreds of thousands of NHS staff acting with the same care, and thought, and precision as Jenny and Luis."
I doubt that they were watching literally every second of the night or even if they were that that somehow guarantees the same occurs every where else in the NHS especially considering the status he has as prime minister as compared to less privileged patients. I suppose that could be a rhetorical device or the NHS may indeed be functioning that well.
I do confess that the whole business grieves me. For some reason I have been thinking recently of something my mother said, late in life, about the boys in her chemistry class during World War II. That she remembered their names and how they went to war and never came back. I am grieving. My niece who works in a large hospital here says that nurses at that hospital are able to check on patients once every four hours. She works there. I don't know why she would lie about it. There is a shortage of PPE and the states are bidding against each other for it. Then sometimes the federal government seizes PPE after states receive it.
From watching John Campbell I understand that Johnson lost time in enacting social distancing and talked about herd immunity as a solution where people would die in the process of attaining that. I blame people like Boris Johnson who have minimized the severity of the problem and acted later than they should. The sight of him unctiously praising the NHS--and I'll grant that they deserve praise--while at the same time he almost sent the UK down a path where even the NHS would be overwhelmed is painful to watch.
ETA: I think I'm reminded of what my mother said because of the feeling of helplessness. I imagine she felt helpless, too.
