About 14 years ago, age 47, I earned the dubious distinction as the first to jump off from center span of the newly constructed Ringling Bridge in Florida. I made top story that day in the local news. Contrary to public reports, I did not get arrested. I did get slightly injured.
I stepped off, right foot forward, dropping about 80 feet in less than two seconds. I impacted the roughly 11' deep murky water, my falling speed in excess of 60 mph at impact, arms out like two wings. As a younger man, I had extensive cliff diving experience in Jamaica. I also use to live in a 4th floor corner condo where I would step off a balcony into an 8' deep clear pool.
I had two close friends as spotters, one more focused than the other. I also had an unsuspecting support crew at the bottom, fully engaged in demolishing the pre-existing adjacent bridge. I did not know it right away; the impact dislocated both arms. I rode a construction barge to a nearby bait shop. Paramedics treated me like a criminal. They strapped me to a gurney and took me an emergency room. I had extremely good major medical coverage. I only paid $50 out of pocket. A specialist maneuvered my arms back in place. I left the hospital that night. It took about 8 weeks before I could resume playing basketball. My bench press temporarily dropped from 250 to 125.
The chief paramedic, after we arrived at the emergency room, insisted the admissions clerk write down - 1. No drugs. 2. No Alcohol. 3. Not psychotic. 4. Not suicidal. Today, I realize he made one mistake. I absolutely had psychosis! I now work hard to break what I call "the Cycle of Stupidity".
Rationale people, IMO, would not take on stepping off/jumping off bridges from heights where injury becomes probable and problematic.
