Up until I got this RA, I've been remarkably healthy, don't normally get the flu, but Hub and I both did last year. I got well in just a few days, he got pneumonia.
He has a fair set of allergies, too, and only had surgery once, for an accidental injury to his shoulder. Last year's flu was the first time I recall him being sick.
We have not had the flu in years, not since we started getting the flu shots. Years ago, we caught it from our kids when they were in school, every year, sometimes more than once. Not fun.
