A large number of injuries can be entirely avoided with simple, light protective gear. Many fractures just wouldn't happen.
Here is a great example of surviving an accident that would otherwise have been much worse,
Some of those chunks streaking along during the disintegration of the SR are human bodies. The pilot and the LCO.
I read a detailed account of another SR-71 disintegration. It was written by the pilot. Many people, including the pilot himself, could not believe that he lived through it; but with the right outfit it is amazing how well one can survive.
[Before getting back to bikes, in case anyone is interested in what is going on in this video -- besides some very interesting designs -- these craft, the SR-71 mothership and the drone that is separating from it, are traveling at very high speeds (mach 3+). The first two separations work out. After the third separation, the drone has problems as it lifts off and moves up into the shock waves around it. It falls back into the SR-71, causing the SR to pitch up. At those extreme speeds, pitching up means disintegration.]
Hope some of you enjoyed this clip.
Back to bikes:
I keep noticing, both in the accidents that I have been in, and in accidents that other riders have, that a little bit of protective gear would prevent a huge amount of pain and expense, treatment and down time.
A little padding, weighing almost nothing, could have prevented any number of broken hips or femurs, broken wrists, and broken arms.
The padding can be made easily from closed cell foam pads.
Many downhill racing outfits use this system. Closed cell foam is inserted into pockets. It's very simple to do, and can be done at home. If the pockets have open or partially open tops, it is easy to remove the pads when desired. Velcro attachment systems are also very simple.
Even limited, ventilated padding, well placed, only over the most injury-prone areas, would go a long way in preventing and reducing injuries.
