Generally I only get sick if I take a week off of commuting, but this year that didn't hold up. I got sick a few weeks back. The symptoms weren't bad, but I didn't want to spread anything so I stayed home.

My wife insists it was the flu, but I didn't think so because I didn't feel that bad. However, 2 weeks after recovering, I got a seasonal flu shot and never had any reaction whatsoever. Previously when I got a flu shot I will feel a little tired for a day or two and might get a slight fever, this time, absolutely nothing. So I probably did have the flu before.
