Martin Luther King BTW died when he was still several years younger than Obama is now.

People just don’t see the difference in type between the different kinds of statements—whether or not the domains of the nouns are specified, for instance. It’s like how in fontaddicts people often make wildly incorrect guesses when asked to identify a font: they don’t have the training to tell the differences. Both book knowledge and practice are necessary.
