I would think that if you were going to kill yourself, you would pick a method that was fairly quick and painless:

A man has been found alive after being chained to a tree in the remote woods of West Vancouver, B.C., for six days in what police are calling a bizarre suicide attempt.
Police say hikers looking for their runaway dog Tuesday evening heard the pleas of a man calling for help in a remote area of Cypress Bowl Road.
The 48-year-old man in distress could not be reached because of the rough terrain, although he was able to tell police he had gone there six days ago to commit suicide and had chained himself to a tree.
