Everyone I work with gets it every year and then they complain about how they feel bad, and then half of them end up out sick for weeks at a time after that anyways. Probably due to the fact that we are exposed to a huge number of people who are not healthy, being at a public library all day. I don't get sick. Take a regimen of garlic, multivitamin, sunlight, exercise, hand sanitizer, and you don't come down with anything.
