In case you haven’t seen this:  A guy in Omaha, Nebraska talked a woman down from jumping off the Bob Kerrey Pedestrian Bridge, which is some 52 feet above the Missouri River.

He happened to be live streaming when he saw her leaning forward on the railing and ready to jump.  He very calmly approached her and convinced her to let him help her come down.  She thanked him later for saving her life.
