Most suicides by hanging, even in jail or prison isn’t what you think. Yes they tie something around their neck, but, not stepping of a stool or chair. Instead they lean forward or slouch forward or down while sitting and just cut off the blood flow to the brain, quite painless, you just pass out and die.
One of my son’s closest friends went off the New River Gorge bridge in WV. One of my good friends went off the New River trail bridge. He ran on that trail all the time.
