Poisons

I remember a while back I was talking to someone who said 'alcohol is a poison.' And when I asked why he said, 'because it can kill you if you drink enough.' And here's another example of something that can kill you if taken in large enough quantities from Orac. Too much water can kill you. And as Orac said - it's a truly senseless way to die. Just because something can kill you doesn't make it a poison - neither water nor alcohol should be classified as such - but stupidity as in doing anything to excess can kill you. Or as someone once said - common sense is very uncommon.
