The problem with jumping off a bridge, even one as tall as the Sunshine Skyway bridge in Florida, is that there's no guarantee that you'll die instantly. You may even survive if only for a few minutes or an hour. I found an interview of a man who jumped off the Skyway and lived long enough to tell about it. He said he instantly regretted jumping and that he experienced exponentially excruciating pain from broken bones and hemorrhaging. Fishermen happened to be nearby and pulled the man out of the water. That's why they were able to get the man's story. That quashed all my fantasies of jumping off a bridge to end it all.
