I think often of suicide, actually. I've been depressed of late, and when i feel depressed, hopeless, powerless, and generally uninspired I think thoughts (silly perhaps), such as, "Why am I still on the planet? I'm breathing oxygen other people could be using?!" But I do find that these periods pass, and I have always liked the statement, "Suicide is a permanent solution to a temporary problem". But if it ever came to pass that I were diagnosed with a fatal illness (as though life itself isn't fatal!), I'm fairly certain that I'd cash in my chips. Just don't think I'd be too unhappy about the prospect of dying either. Good topic!
