The appallingly poor treatment, including being left to starve, of thousands of elderly dementia patients in UK hospitals

See this report in the Telegraph. - Doesn't it shock you and make you feel ashamed of the NHS? Why isn't something done about it? We will all be old one day unless we die before our time. Is this the way you would be happy to be treated if you ever suffer the misfortune of developing dementia and going into one of these uncaring hospitals? Why don't staff who are maltreating patients in these ways get identified and punished? - Why are they allowed to get away with it, since this clearly encourages them to continue in the same cruel way?
