What are two ways in which granny had already prepared for death

From the text:

She had spent so much time preparing for death there was no need for bringing it up again. Let it take care of itself for now. When she was sixty she had felt very old, finished, and went around making farewell trips to see her children and grandchildren, with a secret in her mind: This was the very last of your mother, children! Then she made her will and came down with a long fever. That was all just a notion like a lot of other things, but it was lucky too, for she had once and for all got over the idea of dying for a long time. Now she couldn’t be worried. She hoped she had better sense now.
