Now I'm watching a documentary called "The Bridge". It's about the phenomenon of people jumping off the Golden Gate Bridge. These film-makers asked the city for permission to mount cameras to film the bridge over a year's time, but they didn't realize what their real intention was, to capture individuals jumping off the bridge. Evidently the rate of suicides is about 24 per year, so there is plenty of footage. The film also interviews the family members of suicides as well as people on the bridge the day that they jumped.
This is really interesting so I'm getting back to it.
