Just wanted to wish you and Lady Pat all the best. It’s terrible to have all those worries on top of worrying about your health.
As for the NHS, it isn’t perfect and I think there are tweaks that could be made, but my only (touch wood) experience has been with the late Mr A, who had bowel cancer and an aggressive form of dementia. The care he got was outstanding. In fact my only gripe was that he got too much care at the end and he should have been allowed to die earlier than he did, but that is a real first world problem.
