Not seeing how it helps and saying it hurts is a completely different thing. Forgive me for trying to offer some thoughts in answer to a question, I forgot that if something has already been answered it mustn't be discussed again. . . (who was Newton anyway when he said something about gravity; they had already decided there was none! and he offered his opinion, cursed wretch!). Just in case srawls responds to this, which he probably will, I'll just go ahead and say this: shut up, you're an idiot.
