Yes we do have to be careful about fire, I should know. I was writing an essay on Arisotle once, and it was so hot it set my electronic typewriter on fire and burned the room down...well that's what my lecturer told me when I mentioned the Greek kid in the room next to me bought about 600 candles and set the place ablaze when he left the window open. Dafthead. Fire kills fast, its not the flames, its the smoke.
