I finally got the flu. First time in my life. It was weird--I thought I had a stubborn cold. I didn't have any fever, chills, or coughing but my heart rate was up. I could only do so much and then I would feel wiped out. That's what tipped me off that I might have the flu and went for a flu screen. I had it 3 weeks ago and I'm still recovering. My knee joints are very stiff and tender. This flu was very, very mild but it really settled into the joints. So much for my perfect record.
