These things exist all over the world. In Australia, they're called "swag".

comment How far would you need to fall for it to be fatal?
Concerning the Vesna Vulović case, note that she was not in free fall, she was inside the plane when it crashed after falling the distance.

comment How to overcome mental hurdles of adventure trauma?
It sounds like you're asking how to deal with the immediate situation where you're shaken by an accident, rather than long term fears. If so, the comparison to PTSD is completely wrong and the word trauma itself is misleading. The question would be easier to answer if it were more focussed.

comment Is it true that, in cold conditions, you will freeze faster wearing wet clothes than not wearing any?
@РСТȢѸФХѾЦЧШЩЪЫЬѢѤЮѦѪѨѬѠѺѮѰѲѴ: that has nothing to do with insulation though. And I am extremely skeptical of claims that the evaporation has a stronger effect than the insulation provided even by wet clother, for anything but the most flimsy of garments.

@РСТȢѸФХѾЦЧШЩЪЫЬѢѤЮѦѪѨѬѠѺѮѰѲѴ: the wet clothing is still surrounded by air - your argument does not, heh, hold water

comment How to overcome fear of falling in lead climbing
Obviously that's different for different people, and the book is necessarily written for those who care enough about progress to buy a book. But I don't think going out of your comfort zone often automatically means you don't have fun, and I doubt taking progression too serious makes more people quit climbing than a lack of results despite lots of training.

comment How to overcome fear of falling in lead climbing
@Liam: the idea is to A) desensitize yourself to the negative experience so that it becomes less scary and B) change failing from something negative to something positive (because it helps you get better so that you end up failing less often). Specifically, for optimal progress MacLeod suggests spending the majority (maybe two thirds) of your time doing things at least slightly outside of your comfort zone.

comment How to overcome fear of falling in lead climbing
@Liam: Hm, I recently read Dave MacLeod's "9 Out of 10 Climbers Make the Same Mistakes", which argues that exactly the opposite is the case. Namely, that the most beneficial improvements are always in the areas where you are weakest, and that you can only truly improve by going outside of your comfort zone while looking for "positive experiences" is a trap that prevents you from working on your weaknesses.

comment Which knot for climbing: figure eight, yosemite bowline, bowline on a bight?
In my city there has recently been a fatal climbing gym accident, the second ever, which was definitely due to an improperly tied knot. And the previous one was caused by top rope climbers using a carabiner between the rope and the harness (instead of re-tying) and clipping that into the wrong part of the knot.

@amphibient: a simple plastic liner is still rather poor insulation.

comment What's the difference between water-resistant and waterproof?
There's a saying among sailors: "Waterproof means that once the water gets in, it can't get out again."

comment What's the UPF of a T-Shirt or jeans?
That would be for a white cotton shirt; I doubt that a jeans lets a significant amount of UV pass.
