I never used to get them, and would usually have some sort of nagging cold or respiratory congestion during the winter. I walked by the flu shot room at work when they had them this year, and no waiting. I went in and got it, and have been perfectly healthy this winter despite having two young children passing several illnesses around the house.
I know colds and flu should have different causes, so maybe it's a coincidence. But, I'll keep getting them until I have a reason not to, that's for sure.
