There was a recent case of an older man, though only in his fifties I believe, who was an accomplished film director ... I forget his name. I also forget which bridge he jumped off, even though I looked it all up in Google Maps at the time. LA or SF.
The striking thing was that he was still very fit, and was seen to stop and put on climbing shoes, then without hesitation, scale the tall fence and leap from the top. Maybe he had just learned he was dying or something.
