Another coincidence just occurred to me. Ernest Hemingway also committed suicide at 61, after a severe bout of depression.
Perhaps, like Hemingway, Bourdain was depressed about losing his "edge" - i.e., depressed about age-related loss of youthful skills (mental and/or physical)?
I dunno, just speculating.
Hemingway was dying of cancer, IIRC.
It cannot go unsaid, however, that while Hemingway may have lived an enviable life, he suffered horribly as well, with deep depressive mood swings and drunkenness. But despite his tortured past, at 61 years of age, he appeared to have overcome his many demons. He was at the pinnacle of celebrity when he killed himself. He could have been no more successful or famous. He was a living legend. So why was that not enough for him?
Its when perfectionists fail to adapt that problems occur. This maladaptive perfectionism is one of the driving forces behind highly prosperous people who take their own lives.
