Now all I need is a brain and some courage

Despite comments by a few of my former students to the contrary, I do have a heart (see below for evidence). Last week, my heart started having PVCs (premature ventricular contractions). The pulse feels like it's skipping beats. By themselves, PVCs aren't bad, but they could be a sign of problems. So, the doctor decided to hospitalize me for observation and to run tests. Fortunately, all my tests have come back indicating I am healthy, and I have the go-ahead to continue my marathon training. It was a bit of a scare, though, and poor Kristina gave tremendous support despite having to sleep alone 3 nights (once when I was in the hospital and 2 nights after they injected me with radiation for a test).

Here's an ultrasound image of my heart.
It's turned upside-down to show the heart in it's proper orientation.
