I just got off the phone with the doctor at Mercy Hospital. It looks like the results of my echocardiogram were negative for any heart-related issues and positive for extreme awesomeness and excessive genius-like abilities. That's a good thing at least. Like I mentioned previously, although my father had heart issues growing up, I was always healthy myself. In fact, before I was transported to Mercy by ambulance, it was the first time I'd been in an ambulance or been seriously hurt/injured since around the 8th grade, when I was paralyzed in a martial arts accident.
Hopefully, it's the last time I'll be in an ambulance. Thanks again for your support.
