I have nothing to add other than, "good for you for lacing up your shoes everyday and going out there and trying to heal people." I have a couple MDs in my family and they are good people too.
I've gotten the impression that it's a huge part of their own health, (mental and physical), to leave their job at work, though. You need to get home and go to a baseball game or otherwise cross over into the *happy world* to stay sane. Good for you for caring.
