An important insight, which unfortunately often goes unnoticed:
I’m sure most of us know of people whose parents have been ill and ‘at death’s door’ for a very long time and when we hear the news of their eventual deaths, it comes as no great surprise. Often, the wonder is, How could they have lasted so long?
When that person is YOUR mother or father, however old, their dying is a shock. In fact, I would say that the oftener an elderly parent has diced with death and survived, the more it can seem like they are invincible.
