A comeback doesn't always return you to the same address. There are runners who came back as swimmers and cooks who came back cooking sitting down, and every one of them would tell you the second life was not a lesser one.
The setback gets described in detail because it has a date and a diagnosis attached. What follows it is harder to summarise, which is precisely why it gets undersold.
What comes after tends to be wider than what was interrupted. More people in it, and a much clearer sense of what is actually worth the time.
