My mother works in a nursing home. She has been around the dying most of her life.

She considers it quite ordinary that people need to be "ready" to die. They will not die unless they've literally said goodbye to their loved ones, in many cases, and have literally been told that it's okay to go. Or until they are actually with their loved ones, or even some artifacts.

My great grandmother would never go anywhere without her purse. She was famous for having so many. She was very senile in her last years, and when she died she did so around some family members, and only after she had them go get her purse and her car keys.
