Over the past few years I've gotten sick more times than I'd prefer, despite the fact that I try to be pretty careful with handwashing. I don't normally get a flu shot but was wondering if maybe I should try it this year. The thing is though, whenever I get sick and go to the hospital, they've never actually told me I had the flu. So I don't know if any of my ailments has actually been the flu, and if there would be any worth in getting one. Thoughts?
