I agree that there is something special to be said for realizing the value of life as [@Gunther] noted, [@LeeRoy]. I have had a few brushes with both sides of it, but three in particular stand out.

Of my injuries, the most severe and notable I experienced was in youth, where I had been accidentally poisoned. I was rendered unconscious for a few days and was failing to improve, read becoming worse, and was unreaponsive. However, to my perception and as naive as it was at the time, I had gone on a tour of the cosmos and the infamous "life before one's eyes" type experience. Of all the hallucinations and delusions I have ever experienced, even compared to other near-death encounters, none compared to it. It was both the most fascinating and terrifying experience of my life, to which I recall the only real underlying understanding I had was that this was "the end", whatever that was to mean, but it was not yet the time. 

For being no more than the age of six or so years, no more than eight, and one of the few things I still remember at all, I regard it as great support to the idea of near-death experience. The second far, far later instance was similar in that it was a twilight place filled with strange and bizarre sights and ended by a sudden jolt back into the corporeal, as was the third and most recent. Each instance was unique and personal, but all had similar behaviors and themes. In this day I mostly view them as part of what created my understanding of the matter.

Yet oddly I have never broken any bone in my body. I have however, been carved all too many times. At least those heal given they are flesh wounds.
