I have yet another idea, but it might not be too healthy...

I know that it is impossible to kill yourself by holding your breath. You will simply pass out. Well, what if one did maybe ten minutes of some good hypnotic imagery, and then take a breath, but not a lung-full and just hold it until you pass out and go instantly unconcious.

Now, I haven't tried this and nor would I recommend it but it's just another one of my odd ideas
