I'm happy to hear you're doing well. Keep up the walks. When I was seeing a shrink, he was all depressed one day because of a study that showed that exercise worked as well as psychiatry. I told him he had it all wrong. He should advertise: "Psychiatry, it's as good for you as exercise!"
Also, glad to get some firsthand info about the National Health. Doctors in the US, most of whom are millionaires, constantly tell terror stories about the National Health, but if we elect Obama, then I think America will follow the rest of the developed world with some kind of socialized medicine.
