I disagree with Xenia on a lot of things, but I don't think that she "hates", albeit you might tag it as such. There is a view point that follows the evidence. Evidence is factual, impartial, based on numers and third party science, peer reviewed rather than the gurnings of social media.
The basic health of the nation, in all social classes, for all levels of wealth and education, was at its best during the years of rationing for WW2 and a few years after, when regardless of how much or how little you had you were entitled to a basic minimum ration: 2oz butter, 4oz bacon, 2 eggs, so much flour, and 6oz (I think) of meat per person per week. The rest you grew yourself, or someone in your family did. It was lean pickings for everyone, and no one got fat on it, but no one starved either. And yes, it was normal to buy a little extra sugar or flour and another egg privately, if you could, to make a cake for an important celebration.
And the NHS was created in 1947 to cater for that country, where most people did hard manual labour at home or at work, and few lived more than 3-5 years past retirement. Where there was no treatment for cancer or infertility, not many antibiotics, no transplant surgery, no hip replacements. In the days when the doctor looked you in the eye and said, "Mrs Smith you have xxxx. We can't treat it, but we can relieve the discomfort."
Now we're treating the diseases of ease and affluence and too much good food and good living, in an increasingly elderly population. It's progress, but at some point, we all need to consider how much the extension of life is value-adding at a societal level. We all know how much we love our parents and grandparents and value them as individuals, but extending life into a twilight zone just because we can't bear to say goodbye is destructive to the necessary renewal of life.
