I actually have a heart condition. My docs think it's neural, I have additional pacemaker cells or some shit.  It gives me extra heart beats on occasion. My docs all tell me they know it's not an issue because I run half marathons, and I'm training for a full.  One put it this way, "If your heart is healthy enough to run a half marathon, you aren't going to drop dead on the couch.". I go to the caridiologists for regular check ups so we can keep tabs on it, every other person waiting is a fat fuck with cardiomyopathy.  Wheezing on death's door at age 25.
