People "died" all the time. ... Parts of them died when they made the wrong kinds of decisions-decisions against life. Sometimes they died bit by bit until finally they were just living corpses walking around. If you were perceptive you could see it in their eyes; the fire had gone out ... You always knew when you made a decision against life. ... The door clicked and you were safe inside- safe and dead.
