It's a little scary, at times, when you realise just how thin a margin you live by. When you are forced to notice that your entire body runs on a very tight set of parameters, and a single deviation from one of these parameters can lead to some serious issues.
A palpitation can feel like many things, depending on how serious it is. For me it felt like someone reaching inside my torso and flipping something upside down, and all of a sudden my lungs were just bellows. All they did was suck stuff in and push it out again. Breathing was something that I did twenty seconds ago.
I recovered, obviously. I'll be okay. I'm still not totally on my feet - doc's orders, I'm not work-healthy until this time next week, and I'm on a caffeine and energy drink restriction (which is killing me). Also the usual spiel about eat healthier so on so forth.
He told me himself that were my heart weaker, that might not have been a palpitation at all. It could have been something a lot more serious. I count my blessings.
So I'm sick again. Mostly stuck indoors again, though almost certainly for less time than before.
