I believe there is something after death, but I also believe that in our current living state, we are unable to grasp what it truly is. Before I tell this story, the first thing you should know is that prior to this event, I was pretty much an atheist. I say 'pretty much' because if I had proof, I would change my stance, but at that point proof had never been presented.
Two years ago I got sick, like really sick. I had a lung infection so severe that I had a team of doctors trying to figure out what kind of infection I had and how to treat it. My kidneys were shutting down and my lungs were so full I was drowning on the infection. They did eventually figure it out but I was in hospital for three weeks being pumped with massive amounts of antibiotics while tubes were inserted into my lungs to drain the infection. I lost almost all of my muscle mass. My legs were so weak that it took me a month to learn how to walk again. It took three months after my hospital release before I could return to work and six month to a year before I really felt like myself again. Most of my hospital stay is a blur, I was on morphine for the first few days and I was really sick after all, but there is one memory that really stands out. There was nothing special going on, I was just laying there in my bed thinking about all of the events that led up to my hospitalization. All of a sudden something just clicked, and it was like I had an understanding of something I could never grasp before. It was like I had figured out how the world works, at least in some respect. It sounds kind of ridiculous now that I retell it, and you might say, "oh, it was the drugs" or "You were delirious from the sickness" and maybe I was, but it has never felt that way. In fact, much of how I felt that day has dwindled in memory, particularly since so much of that experience is a blur, but something certainly stayed with me. That understanding was of where we fit in the scheme of the world, and a certainty that there was something running it all, that there had to be something running it all. Maybe it's God, maybe it's something completely different, but at the time I was sure it was something. That same understanding made me sure that we are not done being when we die. I don't claim to know what happens to us when we die, but I am sure that we don't just end. So I may not believe in heaven or hell, I do believe there is something.
For the most part, the answer is yes. I'm a healthy weight again and I suffered few ill effects. My doctor was actually really surprised at how quickly I bounced back. The only thing I find now is that even though I have built up my endurance, I will still start huffing and puffing while walking up the smallest of hills. I'm usually fine, but it sounds like I'm ready to keel over.
