Surely one reason is that they have a much better educated and physically fitter population than most of Europe. The don't have as many obsese people and smokers. They have lower heart disease and cancer rates than most other countries. To top it all they are much better at following rules than we are. I don't have the stats to prove this but I have spent a lot of time there and my strong impression is that Germany is years ahead of the UK in most areas of infrastructure and presumably they have better health care as well. It is just a more advanced country than here.
