I beleieve that if you know you are going to die and have a certain amount of time left then you must be suffering and in pain for the time you have left
As you get older you become more at ease with facing your own mortality. I'm at the point in my life when I really should be planning to take care of some things. Hell, I hope I still have 30 good years left, but there are things I still want to do before I die. If I knew in advance of my death time, I'd be sure to take advantage of that time.
