I've hiked through a lot of forests ever since I was a kid and have a method, often criticized, but that has never injured me, of going down difficult terrain. I more or less glide down at a constant speed, putting my feet in places to apply upwards force. It helps a great deal that I have very flexible angles and can bend at near 90 degree angles. I usually get down very quickly and without fuss, whereas the slower more deliberate method tends to produce bigger falls. You tense up more when you're going down like that, and are more likely to produce uncontrolled fall, which is what kills you. If you can control your fall (throw yourself lightly at a patch that will stop you quickly and not injure you) and go a bit limp to disperse energy quickly, you can fall a lot more than most people but get injured less. I learned this technique from skateboarding. The idea is to learn to do a controlled fall whenever you're in danger into a safe area, rather than possibly risk an uncontrolled fall.

I've been called an idiot for doing this but I have never broken a bone nor had significant injury while hiking.

Anyway, my point is, sometimes just letting the movement flow naturally is the correct thing to do, even if it means the speed involved/perceived danger is higher.
