Seeing as I'm getting older, and also seeing as I'm fortunate to have decent health insurance, I decided to have a medical checkup. At the checkup, my doctor found what he called a "slight irregularity" in my EKG. He said it was likely nothing to worry about, but as a precaution, he sent me to a cardiologist to get a stress test just to make sure.
It turned out that my ticker is perfectly fine. The stress test confirmed that. Personally, I think all the wires they had hooked up to me were superfluous. I figure if the stress test didn't kill me right then and there, my heart is fine.
I hope to be able to post more in the weeks to come.
