personally-and this is speaking as a subscriber to scientific american , here-i feel very sorry for the professionals whenever they find another confusing skull , something that belonged to the wrong sort of people , or whenever they find statues or artifacts that confuse them-for they 'll talk about the odd , but they wo n't talk about the impossible , which is where i feel sorry for them , for as soon as something becomes impossible it slipslides out of belief entirely , whether it 's true or not .
