In the security world everything is a compromise, as there are no absolutes erm you want an absolutely secure health service, don't have a health service, don't let ever give any information out, erm if you fall ill away from your home er you're called into a hospital, you would like the thought that er the hospital can ring up your doctor and get information about you fairly quickly you don't want to have a whole bureaucratic erm apparatus saying no that information isn't available.
