not to be morbid or off topic, it has been my experience that people generally depart in either one of two ways. The sudden, unexpected departure which is terrible for the survivors. if you note, most have offered their prayers and condolences to those in this situation. Then there is the long, slow downhill slide which can be painful and often involves ongoing loss of mental and/or physical abilities. Allows for closure, getting one's affairs in orders, goodbye's, etc. but still involves suffering for all. For many of us, door #1 seems the preferrable of the options if given a choice, which we aren't.
