There are many important milestones in life - reaching 16 so you can drive, reaching 21 so you can drink, getting married, having kids, buying a house, turning 30, turning 40 and so on.
These we can predict.
But once in a while, a milestone smacks you upside the head and you realize it was coming, but you never saw it approaching. Or, perhaps, even knew in advance that it was a milestone.
Today, I reached such a milestone. For the first time, my car insurance payment was less than my life insurance payment - $95 versus $135 dollars.
