Hang-gliding accident:
Don't do this! At least, I am strongly advising you against it. I have serious injuries (from something else), and some of the people online I have been looking at for pain control issues (who are people with serious injuries) have gotten them from hang-gliding accidents. Broken collarbones, shoulders, backs, you name it. I also "know" (meaning people online) people which such injuries from falling off cliffs. These particular people who fell off cliffs also have internal organ damage.
This is far too risky, and from experience, a body covered with serious injuries is worse than death itself and is sure to make you want to die, but you are very crippled now and very limited in your options, and your life will be beyond miserable, from my experience.
