because you can still pull yourself up when it starts hurting too much, i know i can
Maybe you can. I have my doubts, but it's not impossible. But how many people can do that in general? One in a hundred? One in a thousand? It's like elite athlete performance. If you tell an average person to pull themselves up on a piece of rope just by the sheer strength of their arms and hands, without using their legs or any other support, it's a pretty impossible task. It's not typical at all. You don't see examples of this happening, almost ever. In fact, you're the
only person I have seen so far who claims they managed to do this. It's usually either the anchor point braking, or there is something people manage to stand back on.
If you really want to be helpful, and make this a learning opportunity for others, you could also include some other details about your setup as you weren't too specific. You haven't mentioned what kind of rope and what knots you were using. Also, was it really full suspension? Was there nothing beneath you and was your foot not touching the ground? Was there nothing else around that you grabbed? Did you not grab the noose and put your hands between your neck and the noose when you stepped off?
Nothing is 100%. People even survive gunshots to the head if the bullet goes through the right way, or high falls in rare instances. But these are still very-very rare. And full suspension hanging's lethality rate is still among the highest. In the top 3 or so. Regarding pain, experiences vary too.
