I don't have a lot of intimate experience with suicide, beyond a few aquaintances and a few phases when I was younger.

The various links are dead for me, and I would be interested if anyone could provide them.

Also, Wikipedia said that a many people that commit suicide have metal health issues. I also don't know much about mental health, but I think it might be fair to say that many people who commit suicide may have been much better off staying alive due to the possibility of future treatment or cures that might result in a situation of not wanting to commit suicide, in these cases.
