I know a girl, my 'Viking friend' that landed upside down with a tractor on top of her. Just about everything that could be broken was broken. She ended up a thrill seeker because anything that would have killed her was also a blessing in disguise. Constant chronic pain at the maximum of what you are able to endure and live. The choice: painkillers and zoned out, unable to do much of anything or no painkillers, continuously in pain but at least conscious. She eventually learned how to deal with it, found a job that took her all over the world and is now happily married. One very impressive person.
