My dad knows how to do that...but he was a career electrician, who learned that work from his dad, since his teens, and he just retired 2 years ago.
On the other hand, He doesn't know how to put together a modern desktop (although that has more to do with him never having had to do it. If he wanted to learn, I could teach him myself pretty quickly, but seeing as how I know how, he doesn't have to learn )
He just says "Boy! Fix this thing." (I'm 32 and he still calls me "boy" )
