Ok then, to almost actually dying... I was a big bike rider back in my twenties, and unless I absolutely had to drive, I rode my bike. School, work, shopping, everywhere. So one day I'm riding my bike to the bank to deposit a check. I'm crossing a crowded busy road with traffic mostly stopped at a light about a hundreds yards down the road. A truck driver slows and waves me across and I stupidly went, promptly being hit by a pickup that was coming up beside him. I was rushed to the hospital, but while I was in pain and clearly banged up, I didn't seem to have any actual severe wounds. They checked my everything and even x-rayed me - all clear - and I was sent home. One of my old frat buddies drove me home but I was obviously a mess and he didn't leave. Eventually my then live-in girlfriend, who was an ICU nurse, came home from work, saw me and started doing her own examination. My lung had slowly collapsed from internal bleeding, which she quickly diagnosed. And back to the hospital I went, where they stuck a tube in me and drained it all out. The reason it hadn't been caught earlier was that it just wasn't enough at the time for my lung actually fail and it to show up when they checked my breathing or on any scan. She said that if I had stayed home about another 3 - 4 hours longer, I would have simply died.
