By the way Leroy, I think most don't quite get the reasoning behind the question. It is not the lack of builders but rather the lack of the ability that is the real loss.
When I was younger me and the boys would grab the cane poles, some bread, and head for a lake. Same as I did with my father and he with his father. Now a days no one fishes from the bank in their quest to catch those big ones. Never do they ever think the biggest one caught was simply the time spent on the bank with one's father and/or grandfather. Those are the type of things that are being lost and likely never to return.
One of the first photos on my current build was my grand daughter at my build table. She has more questions than an encyclopedia has answers, but what precious times we have at the table.
