As someone who has gone through similar phases in my life, and have tried something as dramatic as jumping in front of a train at one point of time, I found the article to make a lot of sense. It's amazing how animals don't have an idea of suicide. At least it hasn't been shown yet. Yes, I know there's some kind of hampster or lemming or something which jumps into the ocean somewhere in the world in herds, but then no one knows why they do that. Certainly not to get rid of life's worries.
It's quite intriguing what drives someone to the brink; that makes one take the step of killing oneself. In hindsight, I can't remember what made me think of it.
Even the Terminator said 'I cannot self Terminate'. Why us ?
