Ha. The oldest great grand daughter is age 12 and very beautiful, if I say so myself. So your comment could very well happen in the next decade-provided we all live through this nonsense.
I met an almost 50-year-old on a job site right before Covid who had a grandson who was 12.
So I ran the numbers.
If he has a kid at 24, she will be 62. When that kid is 24, she will be 86. If 110 is the new 80 in the future, she can be a great great great.
The thing is, she was still married to the father of her kids, her kids were still married. They all got themselves into good blue collar jobs early.
