I heard something very interesting about people who commit suicide by jumping off buildings, bridges, etc. Supposedly, during the plummet to the ground, the person naturally gets an extreme adrenaline rush. This rush causes a feeling of euphoria, and makes the person feel good about himself, and consequently he begins to regret his decision to jump. Unfortunately, by that time it's usually too late. Oh well.

No idea how someone could possibly know that information. Maybe from people who have tried to jump but ended up surviving? I don't know. I just thought it was kinda interesting.
