Adam, the blogger, is compiling materials for his doctrate. He looks at pain from all possible angles from outside in and from inside out. Did you know that there are five, that's right; five distinct kinds of congenital insensitivity to pain? Do you know why red-haired fair-skinned people are more sensitive to pain?
Did you know there was such a word as "pleonasm"? It means, superfluity of the verbal kind. The inverted word, "neoplasm," with which we are more familiar, means superfluity of the cellular kind.. (I love wordplay, please forgive.)
