What are the facts? Again and again and again, what are the facts? Shun wishful thinking...avoid opinion...facts are your single clue. Do you have to be dying to have a near-death experience? Is a yawn a silent, natural scream for air; and if a little oxygen is good for you is more oxygen better? Can the humble spud kill? Did Galileo drop his balls from the Leaning tower of Pisa? Did a NASA computer really prove a miracle in the Bible actually happened? Is there any substance harder than diamond, and do diamonds really last forever? And, exactly how many Eskimo words for 'snow' are there?
