>>4671734that picture really triggers my autism.
real hanging (easy to do with limited time / equipment almost everywhere) goes like this:
1. you tie a simple noose, or if you want to get fancy, a running bowline, but do NOT tie a hangmans knot, it will not tighten properly when loaded moderately (which is what we need)
and
2. find something to tie the rope onto, doesnt need to be high, breast high is good enough.
fasten rope onto object, put noose around neck, and hang yourself. full suspension is not required. this is referred to as "partial suspension hanging".
the main point is not to break your neck (as in execution hangings, where the hangman knot comes from) or to restrict your air pipe (which is a horribly painful and prolonged death), but to restrict to arteries on your neck that transport blood to and from the brain.
this should result in quick loss of consciousness (under 2 minutes) and subsequent death (under 15 minutes)
it is the same technique used in autoerotique asphyxiation (which sometimes results in accidental death)
for maximum comfiness, put a towel around your neck, otherwise the rope will painfully cut into your skin
