Coronary artery disease. Had a triple bypass last year, and every day since then has been in pain, although it varies and most days it's not that bad. As in, if I don't think about it, it doesn't bother me. The pain isn't my heart, but my sternum, which they had to saw open to get to my heart. I guess that's why it's called open-heart surgery. You know how when the weather changes and atmospheric conditions can make old wounds hurt a bit? That kind of thing. Little twinges of pain every once in a while, throughout the day. Annoying more than anything else. They wire your sternum back together so it'll heal, and the wires stay in, which is freaky.
Technically, I was dead for a few hours while they did the operation. Well, my heart wasn't beating anyway; they have to stop it to do the work, and there's always a slight chance that it won't start back up again when they're done. So yeah, that was exciting.
The worst part is the radical changes to my diet. Red meats are gone. Fats, including most dairy products, gone. Lots of veggies, although they're really boring without butter. I miss ribs. I miss a good cheeseburger. The doctors say nothing is 100% off the menu; a little bit once in a while is okay. There's just a limit to how much your body can process and properly get rid of over time, and everyone's limit is different. Live past that limit for too long, and you end up like me. I just feel like any time I do indulge myself, I'm shaving another couple days off of my lifespan. The best part is that I've lost 30 pounds since then, and of course the fact that I'm not dead.
