The house I grew up in was built in 1926 and the wiring running through the ceiling was wrapped in cloth :D
Similar experience...
I was the bad kid in the family, and had the benefit of always being told to:
"Go Help your Father with the ______ "
And so, I learned how to sweat copper pipes, fix cars, hammer nails, put shingles on a roof, run electrical wires, and put together PVC drains. It's still scary doing it myself though. And I don't have the time to do all that and also all the rest of the day-to-day tasks.
It always hurts my ethos when I need to pay someone to do something I know how to do, but don't have the time... I usually need to pretend I don't see all the things I would do differently.
