...that it is impossible for a person to commit suicide by holding his or her breath?

According to Wikipedia, "if a healthy person were to voluntarily stop breathing (i.e. hold his or her breath) for a long enough amount of time, he or she would lose consciousness, and the body would resume breathing on its own. Because of this, one cannot commit suicide with this method, unless one's breathing was also restricted by something else" (e.g. water, which leads to drowning).
