Had a routine mini-check up with my Doc this morning. My BP is now normal, with medicine. He invited me to have a flu shot before I left. I asked him if they really worked, as I had recently read that they do not.
He said "They probably work a little for the people who don't need them, and don't work for the people who do need them. They're free from the government, so have one if you want."
Free from the government? I got one.
