If you have not gotten one yet, get one. My husband and I and I have had this "crud" for the last week. It has not been fun. When I was teaching I would get a flu shot each year. Since retiring, I have not been as diligent. I think we are finally over the worst part, but still tired feeling, headachey and nasty cough. At least I can walk through my house without getting tired. The worst part of this crud was that I could not read. I just could not focus. So please, get your flu shot.
