Yes, it was a bit of a shock to realize that I had achieved a *reasonable* age to be a grandparent, rather than it only being possible with a couple of teen pregnancies in a row. But I was the only one in my family to get married under thirty, and didn't have children until 31 and 35, so 62 to 70+ seems far more reasonable. For now, anyway. I'm sure it won't when I get there.
