The Irrelevant Number

Hello. Just finished reading a very interesting book. "The Number", by Lee Eisenberg, tells about how he moved from the New York area to Wisconsin in his 'later years' (I'm guessing around 60), and what impact that had on his 'number'.
The number in this book is how much money it would take to retire right now so a person could live comfortably for the rest of their lives. It would have to handle medical costs, housing, food, travel, etc. And since no one knows how long they will live, it's a very challenging calculation to make. Especially when inflation is taken into consideration.
So what's your number? Mine is about $2 million if things stay the same. However, the big thing hanging over my head is my kids' cystic fibrosis medication, which is currently covered by the government. If we were ever to lose that, the number would be much higher.
Is the number relevant? More on that tomorrow.
