Interestingly, Jane will probably end up doing the exact same thing as Susan, only on the timescale of years instead of days. She kept those years in prison. If, in one iteration, the years immediately following prison were of some profound importance, she would probably keep those too. In the absence of a solar flair, she would find herself a 70 year old woman whose memories consisted of only the most important selected years from the 10s of thousands that make up her full history.Thank you for the story.
In any case, there’s no way to end up with more memory-years than your current physical age, so it’s only a question of which 70 years to keep.
