I've tried to ask this question before but I guess it was unclear exactly what I was asking so let me attempt this again. I am curious about the space in between stages. If your going with the seven stage guide then it would be the space between the six and seven stage when a person will go from ranting and raving to single word non sequiturs. What is your experience with the crossover? Is the transition like falling off a cliff or more like a slow but steady decline toward their last days?
