I feel so sorry for her sons especially. Those poor boys must be in shock over their mom being fine just two days ago.
My heart and prayers go out to them.
The fact that Richardson was not wearing a helmet may or may not have made a difference in the gravity of her injury. If skiers are moving slowly - say 10 m.p.h. or slower - and they fall on soft snow, they're probably not going to be hurt severely, whether they're wearing a helmet or not. If they're moving faster than 15 or 20 m.p.h. and strike ice, hard-packed snow or another solid object with the head, they're likely to suffer severe injury, and again the presence of a helmet may not make much difference. It's in the middle area - at speeds that are neither very slow nor very fast - that a helmet can play the biggest role. The trick, of course, is that you never know when you're going to be in that gray zone, since even slow beginner skiers can lose control and speed up, and high-speed skiers have to slow down eventually.
Physics makes things trickier still, causing different parts of the body to move at different speeds. Your skis or snowboard may be sliding along at a slow 10 m.p.h., but if you catch a tip or edge on something stationary, the rest of you plunges forward and accelerates. "The body acts as an inverted pendulum, so the upper body moves much faster than the lower body," says Shealy.
Once you do fall and hit, the brain can do much more than just bump the inside of the skull. "You can have stretching of cortical connections or stretching of blood vessels, and that can lead to bleeding," Shealy says. "You can also have linear or rotational acceleration [of the brain]. There's a lot that can go wrong in there."
i found the above excerpts in one of the many articles written on her tragic accident...
her instructor brought her down from the slopes immediately, and was insisting she seek medical attention.....from that i gather he thought it was best to do so...
could there have been something that was dormant, and just exacerbated with the fall?
i also thought she was declared brain dead in canada, and only went home for the final diagnosis, otherwise i doubt the hospitals would have released her body so soon...jmo
