I think if you found a suitable spot that can hold you weight and you won't be found, and just go full suspension, it WILL kill you. May be fast, may take a while, you may pass out straight away or you might suffer for god knows how long, but with full suspension you're pretty much going past the point of no return. There's no "getting it right" involved.
The "getting it right" for us means passing out almost immediately with no discomfort or pain, but without bringing someone back from the dead and asking what it's like, we don't know if that ever truly happens. You can find a new news article about someone successfully handing themselves every day, but we never know if they suffered or experienced everything we on this forum fear about hanging. They probably just weren't as aware as us about the ins and outs of hanging (maybe did it impulsively) and thus may not have had much fear about it until they were already hanging and then it's pretty much game over. I tried to hang but the fear was too much for me to let myself fall into full suspension, so I'll be going with SN, maybe watching a good film or headphones in, and slowly drift off
60 seconds? Is it rare for your neck to break instantly? I'd started to consider it for the first time but maybe not
Neck breaking occurs from drop hanging. There's quite a bit of information regarding this around the forum (you need a stronger anchor point and rope obviously, and you also need a suitable amount of "drop", can't remember the exact height). Seems far more complicated than simple suspension, and survival instinct may be greater, but if you get it right I'm guessing it's instant death.
Again only going off the little bits I can remember from other posts so I could be wrong
