My brother was just hospitalized last night because of severe flu symptoms. Being that it finally hit so close to home, I guess I ought to start taking some precautions. I've been carrying around a bottle of hand sanitizer(one of those "don't need water" soaps), I take a multivitamin, and I don't touch any orifices with my hands(mucous membranes are the easiest way to contract the flu). Any other helpful hints?
